A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline,
during the next 36 hours in the indicated locations. For a depiction
of areas at risk, please see the National Weather Service Storm
Surge Watch/Warning Graphic, available at hurricanes.gov. This is a
life-threatening situation. Persons located within these areas
should take all necessary actions to protect life and property from
rising water and the potential for other dangerous conditions.
Promptly follow evacuation and other instructions from local
officials.

A Storm Surge Watch means there is a possibility of life-
threatening inundation, from rising water moving inland from the
coastline, in the indicated locations during the next 48 hours.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area within the next 24 hours.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.
DISCUSSION AND OUTLOOK
———————-
At 1000 AM CDT (1500 UTC), the center of Tropical Storm Cristobal
was located near latitude 28.7 North, longitude 90.0 West. Cristobal
is moving toward the north near 12 mph (19 km/h), and this general
motion is expected to continue today, followed by a gradual turn
toward the north-northwest late today or tonight. On the forecast
track, the center of Cristobal will approach the northern Gulf of
Mexico coast this afternoon, then move inland across Louisiana late
today through Monday morning, and northward across Arkansas and
Missouri Monday afternoon into Tuesday.

Data from an Air Force Reserve reconnaissance aircraft and NOAA
Doppler weather radars indicate that maximum sustained winds remain
near 50 mph (85 km/h) with higher gusts. Little change in strength
is forecast before landfall. Gradual weakening will begin once
Cristobal moves inland.

Tropical-storm-force winds extend outward up to 205 miles (335 km),
mainly to the east of the center. A Weatherflow site at Bayou
Bienvenue, Louisiana, recently measured a sustained wind of 37 mph
(60 km/h) and a gust to 47 mph (76 km/h).

The estimated minimum central pressure is 994 mb (29.36 inches).
HAZARDS AFFECTING LAND
———————-
Key messages for Cristobal can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC, and
on the web at http://www.hurricanes.gov/text/MIATCDAT3.shtml

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide…

Mouth of the Mississippi River to Ocean Springs MS including Lake
Borgne…3-5 ft
Morgan City LA to Mouth of the Mississippi River…2-4 ft
Ocean Springs MS to Marco Island FL including Mobile Bay, Pensacola
Bay, and Tampa Bay…1-3 ft

The deepest water will occur along the immediate coast in areas of
onshore winds and will likely extend along the coast well to the
east of the center. Surge-related flooding depends on the relative
timing of the surge and the tidal cycle, and can vary greatly over
short distances. For information specific to your area, please see
products issued by your local National Weather Service forecast
office.

WIND: Tropical storm conditions are expected within the Tropical
Storm Warning area along the northern Gulf coast through tonight.

RAINFALL: Cristobal is expected to produce total rainfall
accumulations of 4 to 8 inches across portions of the central Gulf
Coast into the Lower Mississippi Valley, with isolated amounts to
12 inches. Rainfall totals of 2 to 4 inches with local amounts to
6 inches are expected across portions of the eastern Gulf Coast,
along with the Mid to Upper Mississippi Valley and Northern Plains
near and in advance of Cristobal. This rainfall will likely lead
to flash flooding and widespread flooding on smaller streams across
portions of the central Gulf Coast into the Lower Mississippi
Valley. New and renewed significant river flooding is possible
along the central Gulf Coast and into the Mississippi Valley.

TORNADOES: A few tornadoes are possible today and tonight across
eastern Louisiana, southern Mississippi, southern Alabama, and
northern Florida.

SURF: Swells generated by Cristobal will affect portions of the
northern and eastern Gulf coast during the next couple of days.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local
weather office.

center of the cyclone should move across the northwestern Gulf of
Mexico this afternoon and then move over the northern Gulf coast
tonight or Saturday morning.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Some strengthening is expected today, and the depression could
become a tropical storm this afternoon. The cyclone is then
expected to merge with a cold front and become a post-tropical low
with gale-force winds tonight before the center reaches the Gulf
coast. An Air Force Reserve Hurricane Hunter aircraft is scheduled
to investigate the depression this afternoon.

The estimated minimum central pressure is 1006 mb (29.71 inches).
HAZARDS AFFECTING LAND
———————-
WIND: Gale-force winds associated with this system should spread
over portions of the northern Gulf coast tonight and Saturday
morning.

RAINFALL: The depression and rainfall ahead of the system along and
north of the frontal boundary across the Central Gulf coast is
expected to produce total rainfall accumulations of 2 to 4 inches
with maximum totals of 8 inches across the Central Gulf coast into
the Lower Mississippi Valley through Saturday morning. These rains

DISCUSSION AND OUTLOOK
———————-
Satellite, aircraft, and radar data indicate that the eye of
Michael is making landfall just northwest of Mexico Beach, Florida.

At 100 PM CDT (1800 UTC), the eye of Hurricane Michael was located
near latitude 30.0 North, longitude 85.5 West. Michael is moving
toward the north-northeast near 14 mph (22 km/h). A turn toward the
northeast is expected this afternoon or tonight. A motion toward
the northeast at a faster forward speed is forecast on Thursday
through Friday night. On the forecast track, the core of Michael
will move inland across the Florida Panhandle this afternoon, and
across southeastern Alabama and southwestern Georgia tonight.
Michael will move northeastward across the southeastern United
States through Thursday night, and then move off the Mid-Atlantic
coast away from the United States on Friday.

Recent data from NOAA and Air Force Reserve Hurricane Hunter
aircraft indicate that maximum sustained winds have increased to
near 155 mph (250 km/h) with higher gusts. Michael is an extremely
dangerous category 4 hurricane on the Saffir-Simpson Hurricane Wind
Scale. Michael should weaken as it crosses the southeastern United
States. Michael is forecast to become a post-tropical cyclone on
Friday, and strengthening is forecast as the system moves over the
western Atlantic.

Hurricane-force winds extend outward up to 45 miles (75 km) from
the center and tropical-storm-force winds extend outward up to 175
miles (280 km). A wind gust of 130 mph (210 mph) was recently
reported at a University of Florida/Weatherflow observing site near
Tyndall Air Force Base before the instrument failed. A wind gust to
129 mph (207 km/h) was reported at the Panama City Airport.

The latest minimum central pressure based on data from an Air Force
Reserve reconnaissance aircraft is 919 mb (27.41 inches).

A minimum pressure of 920 mb was recently reported by a University
of Florida/Weatherflow observing site near Tyndall Air Force Base.
HAZARDS AFFECTING LAND
———————-
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water has the
potential to reach the following heights above ground if peak surge
occurs at the time of high tide…

Tyndall Air Force Base FL to Aucilla River FL…9-14 ft
Okaloosa/Walton County Line FL to Tyndall Air Force Base FL…6-9 ft
Aucilla River FL to Cedar Key FL…6-9 ft
Cedar Key FL to Chassahowitzka FL…4-6 ft
Chassahowitzka to Anna Maria Island FL including Tampa Bay…2-4 ft
Sound side of the North Carolina Outer Banks from Ocracoke Inlet to
Duck…2-4 ft

Water levels continue to rise quickly along the coast of the Florida
Panhandle. A National Ocean Service water level station at
Apalachicola recently reported over 6.5 feet of inundation above
ground level.

WIND: Tropical storm and hurricane conditions will continue
to spread inland across portions of the Florida Panhandle,
southeastern Alabama and southwestern Georgia this afternoon and
tonight.

With the landfall of Michael’s eye occurring, everyone in the
landfall area is reminded not to venture out into the relative calm
of the eye, as hazardous winds will increase very quickly as the eye
passes!

Tropical storm conditions are expected to spread northward within
the warning area along the southeast U.S. coast beginning tonight
through Friday.

RAINFALL: Michael is expected to produce the following rainfall
amounts through Friday…

Florida Panhandle and Big Bend, southeast Alabama, and portions of
southwest and central Georgia…4 to 8 inches, with isolated maximum
amounts of 12 inches. This rainfall could lead to life-threatening
flash floods.

The remainder of Georgia, the Carolinas, and southern Virginia…3
to 6 inches, with isolated maximum amounts of 8 inches. This
rainfall could lead to life-threatening flash floods.

Florida Peninsula, eastern Mid Atlantic, southern New England
coast…1-3 inches.

SURF: Swells generated by Michael will affect the coasts of the
eastern, northern, and western Gulf of Mexico during the next day
or so. These swells are likely to cause life-threatening surf
and rip current conditions. Please consult products from your local
weather office.

TORNADOES: Tornadoes are possible across parts of the Florida
Panhandle and the northern Florida Peninsula through this afternoon.
This risk will spread northward into parts of Georgia and southern
South Carolina this afternoon and tonight.

TORNADOES

 

Mesoscale Discussion 1559
NWS Storm Prediction Center Norman OK
1229 PM CDT Wed Oct 10 2018

Areas affected…Portions of central and southern GA…north
FL…and southern SC

Concerning…Severe potential…Tornado Watch likely

Valid 101729Z – 102030Z

Probability of Watch Issuance…95 percent

SUMMARY…A tornado watch will be issued by mid afternoon across
portions of central and southeast Georgia, and perhaps including
parts of north Florida and southern South Carolina. A tornado
threat will spread to the northeast as Hurricane Michael tracks
toward southwest Georgia by early evening, after making landfall
early this afternoon.

DISCUSSION…Trends in mosaic radar imagery suggest a new outer rain
band may be developing across southeast into south-central GA (from
approximately 25 WSW KSSI to 25 WSW KMCN). The combination of
high-moisture-content air (surface dew points in the middle 70s) and
surface heating, given the presence of filtered sunshine through
high thin cirrus on the northeast periphery of Michael, is resulting
in moderate instability. Meanwhile, trends in low-level shear per
VAD profile at Valdosta, GA adjusted for storm motions of embedded
cells in the rain bands indicated steady strengthening, with 0-1 km
SRH approaching 300 m2/s2 and 0-1 km shear around 40 kt. This
strengthening trend is expected to persist through the afternoon and
evening and expand northward and east some across central and
eastern GA into adjacent southern SC, and perhaps north FL, as
Michael tracks toward southwest GA. This high low-level shear
environment favors an increasing tornado threat and the need for a
tornado watch to the north and northeast of WW 406.

WATCHES AND WARNINGS
——————–
CHANGES WITH THIS ADVISORY:

The Storm Surge Warnings from Fernandina Beach southward, from
the Aucilla River westward, and from Clearwater Beach southward,
including Tampa Bay, have been discontinued.

The Tropical Storm Warning from the Flagler/Volusia County line to
Altamaha Sound is discontinued.

The Tropical Storm Warning from north of the Suwannee River to the
Okaloosa/Walton County line is discontinued.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Warning is in effect for…
* North of Fernandina Beach to the South Santee River
* North of Clearwater Beach to the Aucilla River

A Tropical Storm Warning is in effect for…
* North of Altamaha Sound to the South Santee River

A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline,
during the next 36 hours in the indicated locations. For a
depiction of areas at risk, please see the National Weather
Service Storm Surge Watch/Warning Graphic, available at
hurricanes.gov. This is a life-threatening situation. Persons
located within these areas should take all necessary actions to
protect life and property from rising water and the potential for
other dangerous conditions. Promptly follow evacuation and other
instructions from local officials.

Interests elsewhere in the southeastern United States should monitor
the progress of Irma.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.

 

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 500 PM EDT (2100 UTC), the center of Tropical Storm Irma was
located near latitude 31.5 North, longitude 84.0 West. Irma is
moving toward the north-northwest near 17 mph (28 km/h), and a
turn toward the northwest is expected by Tuesday morning. On the
forecast track, the center of Irma will continue to move over
southwestern Georgia tonight and move into Alabama on Tuesday.

Maximum sustained winds have decreased to near 50 mph (85 km/h) with
higher gusts. Continued weakening is forecast, and Irma is likely
to become a tropical depression on Tuesday.

Tropical-storm-force winds extend outward up to 415 miles (665 km)
from the center.

The estimated minimum central pressure is 985 mb (29.09 inches).

 

HAZARDS AFFECTING LAND
———————-
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water is
expected to reach the following HEIGHTS ABOVE GROUND if the peak
surge occurs at the time of high tide…

North of Clearwater Beach to Aucilla River…4 t 6 ft
West of Aucilla River to Ochlockonee River…1 to 3 ft
Clearwater Beach to Bonita Beach including Tampa Bay…1 to 3 ft

South Santee River to North of Fernandina Beach…4 to 6 ft
Fernandina Beach to Flagler/Volusia County line, including the St.
Johns River…1 to 3 ft

The deepest water will occur along the immediate coast in areas of
onshore winds, where the surge will be accompanied by large and
destructive waves. Surge-related flooding depends on the relative
timing of the surge and the tidal cycle, and can vary greatly over
short distances. For information specific to your area, please see
products issued by your local National Weather Service forecast
office.

WIND: Tropical storm conditions are expected in portions of the
warning area into tonight.

Rainfall: Irma is expected to produce the following rain
accumulations through Wednesday:

South Carolina and north-central Georgia and Alabama into the
southern Appalachians…3 to 6 inches with isolated 10 inches.
Northern Mississippi and southern portions of Tennessee and North
Carolina…2 to 4 inches.

TORNADOES: Isolated tornadoes are possible tonight along the South
Carolina coast.

SURF: Swells generated by Irma are affecting the southeast coast of
the United States. These swells are likely to cause life-
threatening surf and rip current conditions. Please consult
products from your local weather office.

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1000 PM CDT (0300 UTC), the center of Tropical Depression Harvey
was located near latitude 31.7 North, longitude 92.3 West. The
depression is moving toward the north-northeast near 9 mph (15 km/h)
and this motion is expected to continue tonight. A turn toward the
northeast is expected Thursday or Thursday night. On the forecast
track, the center of Harvey should move through central Louisiana
tonight, then move through northeastern Louisiana and northwestern
Mississippi Thursday and Thursday night, and over the Tennessee
Valley region on Friday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Gradual weakening is expected over the next 48 hours.

The estimated minimum central pressure is 998 mb (29.47 inches).

 

HAZARDS AFFECTING LAND
———————-
RAINFALL: Harvey is expected to produce additional rainfall
accumulations of 4 to 8 inches from southwestern Louisiana and the
adjacent border of eastern Texas northeastward into western
Tennessee and Kentucky through Friday with isolated amounts up to 12
inches. The threat of heavy rains has ended in the Houston/
Galveston area. However catastrophic and life-threatening flooding
will continue in and around Houston, Beaumont/Port Arthur,
and eastward into southwest Louisiana for the rest of the week. The
expected heavy rains spreading northeastward from Louisiana into
western Kentucky may also lead to flash flooding and increased river
and small stream flooding. DO NOT ATTEMPT TO TRAVEL IN THE AFFECTED
AREA IF YOU ARE IN A SAFE PLACE. DO NOT DRIVE INTO FLOODED
ROADWAYS. Please see warnings and products issued by your local
National Weather Service office for additional information on this
life-threatening situation.

Elsewhere, the outer bands of Harvey are expected to produce
additional rainfall amounts of 3 to 6 inches over portions of the
central and eastern Gulf States and 2 to 4 inches farther north into
parts of the Tennessee Valley, Ohio Valley and southern Mid Atlantic
through Saturday. These rains may lead to flooding concerns across
these areas.

A list of preliminary rainfall observations compiled by the NOAA
Weather Prediction Center can be found at:
http://www.wpc.ncep.noaa.gov/discussions/nfdscc1.html

STORM SURGE: Water levels along the northwestern and northern
Gulf coast should subside very slowly over the next day or two.

TORNADOES: Isolated tornadoes are possible tonight across parts of
Mississippi, southern Alabama, and southwest Georgia. Additional
tornadoes are possible on Thursday afternoon and evening across
northern portions of Mississippi, Alabama, Georgia, and into parts
of Tennessee.
