The forecast path shown above is the Bureau’s best estimate of the cyclone’s future movement and intensity. There is always some uncertainty associated with tropical cyclone forecasting and the grey zone indicates the range of likely tracks of the cyclone centre.

Due to the uncertainty in the future movement, the indicated winds will almost certainly extend to regions outside the rings on this map. The extent of the warning and watch zones reflects this.

This product is designed for land-based communities; mariners should read the coastal waters and high seas warnings.

Headline:

Ex-Cyclone Lam has been downgraded to a tropical low. Heavy rain continues over central Top End.

Areas affected:

Warning zone: None.

Watch zone: None.

Details of Ex-Tropical Cyclone Lam at 4:30 pm CST:

Intensity: tropical low, sustained winds near the centre of 55 kilometres per hour with wind gusts to 85 kilometres per hour.
Location: within 55 kilometres of 14.1 degrees South, 133.8 degrees East , 75 kilometres southwest of Bulman and 90 kilometres northeast of Beswick .
Movement: south southwest at 21 kilometres per hour .

Hazards:

Squally thunderstorms are likely to continue over the Top End.

HEAVY RAIN is expected to cause flooding of low-lying areas and cause river rises over the central Top End. Locally very heavy rainfall which could cause flash flooding is possible. A Flood Watch for the Arnhem and Carpentaria Coastal Rivers has been issued.

The STORM TIDE risk for coastal residents between Milingimbi and the Queensland border will continue to ease, however ABNORMALLY HIGH TIDES may still occur at the time of local high tides for the next day or two.

No further issues of this product.

Refer to Severe Weather Warning.

Recommended Action:

The Territory Controller advises residents of Elcho Island, Milingimbi, Gapuwiyak and Ramingining in shelter that it is now safe to leave shelter. Shelters will remain open where necessary and residents are advised to limit movement to essential travel only and proceed with care around affected communities.

Damage has occurred to power lines in affected areas and residents should STAY AWAY FROM DOWNED POWER LINES.

The Territory Controller advises that heavy rain has resulted in swollen waterways, creeks and drains and residents should stay away from these areas.

REMARKS:
192100Z POSITION NEAR 12.8S 134.7E.
TROPICAL CYCLONE 12P (LAM), LOCATED APPROXIMATELY 234 NM EAST OF
DARWIN, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT 08 KNOTS OVER THE
PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS THAT TC
12P IS CURRENTLY OVER LAND. THE CURRENT POSITION IS CONFIRMED BY
RADAR OBSERVATIONS FROM GOVE AIRPORT AND WARRUWI WITH HIGH
CONFIDENCE. THESE RADARS ALSO SHOW THAT THE BULK OF THE DEEP
CONVECTION IS ON THE WESTERN SIDE OF THE SYSTEM. CURRENT INTENSITY
IS ASSESSED AT 65 KNOTS BASED ON OBSERVATION STATIONS IN THE
VICINITY OF THE SYSTEM AND OVERALL LAND INTERACTION WITH HIGH
CONFIDENCE. UPPER LEVEL ANALYSIS INDICATES THAT THE SYSTEM IS IN A
SOMEWHAT FAVORABLE ENVIRONMENT WITH GOOD POLEWARD OUTFLOW AND LOW
VERTICAL WIND SHEAR, HOWEVER FURTHER INTENSIFICATION IS UNLIKELY DUE
TO LAND INTERACTION. TC LAM IS EXPECTED TO CONTINUE ALONG ITS
SOUTHWESTERN TRACK ALONG THE EASTERN PERIPHERY OF A DEEP SUBTROPICAL
HIGH CURRENTLY ANCHORED OVER THE NORTH WEST BASIN. AS THE HIGH
TRACKS TO THE WEST, EXPECT TC 12P TO SLOWLY DISSIPATE AS IT TRACKS
THROUGH THE NORTHERN TERRITORY, COMPLETELY DISSIPATING IN THE
VICINITY OF GREGORY NATIONAL PARK. THIS IS THE FINAL WARNING ON THIS
SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL
BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.//
