APCEDI ALERT Tropical Cyclone 01B (WTIO21) #5, 2005: Tropical Cyclone 01B Dissipated

Tropical Cyclone O1B has now dissipated. Showers, some heavy, were common along the southeastern coastal Districts especially Hambantota and Ampara, but did not cause any significant flooding. Although the area is still getting gusty winds and heavy seas.

The Joint Typhoon Warning Center is issuing statements on another area of low pressure 475 nm east-southeast of Colombo. All interests in the eastern and southern Districts should monitor this system for possible development.

FROM JOINT TYPHOON WARNING CENTER

AN AREA OF CONVECTION HAS PERSISTED NEAR 4.8N2 87.7E2, APPROXIMATELY 475 NM EAST-SOUTHEAST OF COLOMBO, SRI LANKA. ANIMATED SATELLITE IMAGERY SHOWS PERSISTENT DEEP CONVECTION ASSOCIATED WITH AN AREA OF BROAD TROUGHING. EARLIER MICROWAVE IMAGERY ALSO INDICATES A BROAD TROUGH BUT NO CLEAR LOW LEVEL CIRCULATION CENTER. UPPER LEVEL ANALYSIS REVEALS FAVORABLE DIFFLUENCE AND WEAK VERTICAL WIND SHEAR OVER THE AREA. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED AT 1008 MB. THE POTENTIAL FOR DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS IS POOR.

APCEDI will continue to monitor the progress of this and other tropical systems in the Sri Lanka area.
