At 1100 AM AST (1500 UTC), the center of Tropical Storm Vicky was located near latitude 20.6 North, longitude 31.0 West. Vicky is moving toward the westnorthwest near 9 mph (15 km/h), and a turn toward the westnorthwest is expected on Wednesday, followed by a turn toward the west on Thursday. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Weakening is forecast due to strong upperlevel winds during the next 48 hours, and Vicky is likely to degenerate into remnant low by Wednesday night. Tropicalstormforce winds extend outward up to 115 miles (185 km) from the center.

The estimated minimum central pressure is 1004 mb (29.65 inches).

The estimated minimum central pressure is 1004 mb (29.65 inches).

Although the stiff westerly shear (magnitude of greater than 50 kt) continues to affect Vicky's vertical structure this morning, a 1107 UTC METOP-B scatterometer pass indicated that the cyclone is maintaining 45-kt sustained winds well to the east-northeast of the center. Therefore, once again for this advisory, the initial intensity is held at 45 kt.

The ECMWF/FV3 SHIPS intensity models and the deterministic guidance, including the simulated infrared imagery product, agree with Vicky weakening to a remnant low in 36 hours and dissipating by 72 hours due to the persistent strong shear.

The initial motion is estimated to be west-northwestward, or 295/8 kt. Vicky is forecast to continue on this general motion through Wednesday night within the low-level tradewind flow. No significant changes were made to the previous advisory, and the new NHC forecast is based on the HCCA and TVCA consensus ai
