RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 10.7N
139.9E, IS NOW LOCATED NEAR 10.4N 138.5E, APPROXIMATELY 56 NM NORTH-
NORTHEAST OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)
SHOWS FLARING CONVECTION WRAPPING AROUND AN EXPOSED LOW LEVEL
CIRCULATION CENTER (LLCC) THAT IS TRACKING WESTWARD. THE MSI LOOP
ALSO SHOWS THE POLEWARD OUTFLOW HAS WEAKENED OVER THE PAST 24 HOURS.
RECENT SCATTEROMETRY DATA INDICATES HIGHER WINDS (15-20 KNOTS) ALONG
THE WESTERN FLANK ASSOCIATED WITH THE CONVECTIVE CLUSTERS AND
LARGELY RAIN-FLAGGED; A WESTERLY FLOW TO THE SOUTH SHOWS 5-15
KNOTS. UPPER LEVEL ANALYSIS CONTINUES TO INDICATE A MARGINAL
ENVIRONMENT WITH MODERATE EASTERLY (15-20 KNOT) VERTICAL WIND SHEAR
CAUSING THE DISPLACEMENT OF THE DEEP CONVECTION FROM THE LLCC.
NUMERIC MODELS HAVE SCALED DOWN THE FORECAST INTENSITIES ON THIS
SYSTEM TO BELOW WARNING THRESHOLD. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.
(2) NO OTHER SUSPECT AREAS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE. //

News Reports

Two LPAs moving toward Philippines

“One of two low-pressure areas (LPAs) moving toward the Philippine territory is expected to develop into a tropical cyclone within 24 to 36 hours.

According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), one of the LPAs was located 220 kilometers (km) east-northeast of Surigao City, while the other one was spotted 1,220 km east of Guiuan, Eastern Samar, as of mid-Sunday.

The weather disturbance near Surigao City will bring cloudy skies with moderate to occasional heavy rains and thunderstorms over Eastern Visayas, particularly Eastern and Northern Samar.

PAGASA advised residents in these areas of possible flash floods and landslides. It also advised fishermen and seafarers of moderate to occasional rough seas over the Eastern and Central Visayas.

Weather forecaster Gladys Saludes said the LPA is not expected to intensify into a tropical depression as it is already near land.

Meanwhile, the LPA east of Guiuan, Eastern Samar, which is seen to enter the Philippine area of responsibility (PAR) possibly Sunday evening or early Monday, has a high chance of developing into a tropical depression, Saludes said.

Should it enter PAR and intensify into a tropical depression, it will be locally called ‘Ester,’ the fifth tropical cyclone to enter the country’s vicinity this year and the second this month.

Based on the latest forecast models, Saludes noted that the weather disturbance could make landfall over Bicol Region or Samar area by Wednesday afternoon or evening.

“Rains due to the tropical cyclone may prevail over Eastern Visayas starting Tuesday, and over Bicol Region and Samar including Southern Luzon by Wednesday,” she said.

In other parts of the country, the warm and moist air coming from the Pacific Ocean called the easterlies will affect the provinces of Northern Luzon.

Metro Manila and the rest of the country will be partly cloudy to cloudy with isolated rain showers or thunderstorms mostly in the afternoon or evening.” by Ellalyn De Vera
