TROPICAL STORM 12E (GENEVIEVE) ***FINAL BULLETIN*** PUBLIC ADVISORY #14 FORCE THIRTEEN SINGAPORE, SINGAPORE 0840 UTC FRI AUG 21 2020 ...GENEVIEVE MOVING AWAY FROM BAJA CALIFORNIA... SUMMARY OF 0900 UTC...INFORMATION ----------------------------------- LOCATION...NEAR 24.3 N 114.3 W... MAXIMUM SUSTAINED WINDS...50MPH...85KM/H MINIMUM CENTRAL PRESSURE...999MB WATCHES AND WARNINGS ----------------------------------- A Tropical Storm Warning is in effect for... * Baja California peninsula from Todos Santos to Cabo San Lazaro
DISCUSSION ----------------------------------- The combination of moderate southerly vertical wind shear, cooler sea-surface temperatures (SST) near 26 deg C, and dry mid-level air has caused Genevieve to rapidly weaken over the past 24 hours. Very little deep convection remains, and what convection there is has been displaced well to the northeast of the low-level center. An ASCAT-A scatterometer pass at 0428Z indicated one surface wind vector of 43 kt in the northeastern quadrant about 40 nmi from the center. Thus, the initial intensity has been lowered to 45 kt. The 34-kt wind radii have also been decreased in all quadrants based on the scatterometer data. Passive microwave imagery the scatterometer data indicate that Genevieve's center is southwest of the previous advisory track, and the initial motion is now 295/09 kt. The weakening cyclone and its remnants should continue to move west-northwestward to northwestward during the next few days, accompanied by a decrease in forward speed as the system weakens and becomes more vertically shallow. The decoupled remnant mid-level circulation and its attendant moisture plume, however, are expected to move northward today through Sunday, and move into the southwestern United States on Monday. On the forecast track, Genevieve should gradually move away from the Baja California coast throughout the forecast period.
