TROPICAL STORM 18L (RENE) ***FINAL BULLETIN*** PUBLIC ADVISORY #10 FORCE THIRTEEN SINGAPORE, SINGAPORE 1300 UTC SAT SEP 12 2020 ...RENE REMAINS ITS INTENSITY IN THE OPEN ATLANTIC... SUMMARY OF 1200 UTC...INFORMATION ----------------------------------- LOCATION...NEAR 22.0 N 42.9 W... MAXIMUM SUSTAINED WINDS...40MPH...60KM/H MINIMUM CENTRAL PRESSURE...1004MB WATCHES AND WARNINGS ----------------------------------- NO WARNINGS IN EFFECT.
DISCUSSION ----------------------------------- Deep convection associated with Rene appears to have lost some organization overnight. Although there have been several pulsating bursts of convection overnight, the convection that was persistent over the center during the evening is now confined to the southern portion of the circulation. A blend of the latest subjective and objective satellite intensity estimates yields an initial intensity of 35 kt, but this could be generous. ASCAT data later this morning should help to determine if Rene is still a topical storm. Mid-level dry air appears to be the primary reason why Rene has struggled to strengthen over the past few days, and although the shear is expected to remain low today, the dry air is likely to prevent strengthening. On Sunday, Rene is forecast to approach an area of strong west-northwesterly flow aloft, and this increase is shear is likely to cause the cyclone to weaken. Most of the global models continue to significantly weaken Rene early next week, and both the ECMWF and GFS suggest that the cyclone will degenerate into a trough of low pressure by days 4 or 5. The NHC forecast continues to maintain Rene as a tropical cyclone throughout the forecast period, but if the current trends it is becoming unlikely that Rene will survive as a tropical cyclone for the entire 5-day period.
