REMARKS:
242100Z POSITION NEAR 8.0S 38.8E.
24APR21. TROPICAL CYCLONE (TC) 29S (JOBO), LOCATED APPROXIMATELY 73
NM SOUTH-SOUTHWEST OF DAR ES SALAAM, TANZANIA, HAS TRACKED WESTWARD
AT 07 KNOTS OVER THE PAST SIX HOURS. TC JOBO WEAKENED RAPIDLY AS IT
APPROACHED THE TANZANIAN COAST WITH LITTLE EVIDENCE OF A COHESIVE
LOW-LEVEL CIRCULATION (LLC). A 241801Z ASCAT-A IMAGE INDICATES
CONVERGENT SOUTHEASTERLY TO SOUTHERLY FLOW (10-20 KNOTS) ALONG THE
COAST WITH WEAK TROUGHING ALONG 8S. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY AND A 241623Z SSMIS 91GHZ IMAGE REVEAL HEAVY
CONVECTION WITHIN THE CONVERGENT FLOW TO THE SOUTH AND NO EVIDENCE
OF AN LLC AS REFLECTED IN THE ASCAT DATA. THUS, IMAGERY SUGGESTS THE
SYSTEM HAS ALREADY DISSIPATED AS A WEAK 20-25 KNOT SYSTEM. THE
REMNANTS ARE FORECAST TO TRACK INLAND OVER THE NEXT 12 HOURS WITH
HEAVY RAINFALL BEING THE PRIMARY IMPACT TO TANZANIA. 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.//
