At 1100 AM AST (1500 UTC), the center of Tropical Storm Vicky was located near latitude 21.5 North, longitude 34.7 West. Vicky is moving toward the west near 9 mph (15 km/h), and a westward motion is expected to continue through late Thursday. A westsouthwestward motion is forecast to begin by Friday and continue through dissipation.

Maximum sustained winds have decreased to near 40 mph (65 km/h) with higher gusts. Additional weakening is forecast, and Vicky is expected to become a tropical depression Thursday, weaken to a remnant low on Friday, and dissipate Saturday.

Tropicalstormforce winds extend outward up to 70 miles (110 km) from the center.

The estimated minimum central pressure is 1008 mb (29.77 inches).

The estimated minimum central pressure is 1008 mb (29.77 inches).

Hostile vertical shear of 50 to 60 kt has finally taken a toll on Vicky. A 1227 UTC ASCAT-B overpass showed peak winds of 35 kt north of the center, and that is the basis for the advisory intensity. The strong shear is expected to continue while Vicky moves over marginal 26-27C SSTs, so additional weakening is forecast. Vicky should become a tropical depression in around 24 hours before weakening to a remnant low in about 2 days, with dissipation expected by day 3. However, the timing of when organized deep convection will finally cease is difficult to determine, so its is possible Vicky could weaken faster than indicated here or hang on a bit longer.

The initial motion estimate is more westward, or 270/08. Vicky should continue moving westward for the next day or two before turning west-southwestward in the low-level flow. The new NHC track forecast is south of the previous one and is close to the new multi-model consensus aids. The ASCAT data were also used to modify the initial 34-kt wind radii.
