At 800 PM CVT (2100 UTC), the center of Tropical Storm Vicky was located near latitude 19.3 North, longitude 29.5 West. Vicky is moving toward the northwest near 7 mph (11 km/h). A continued northwestward motion is expected through early Tuesday, followed by a gradual turn toward the west by Wednesday.

Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Gradual weakening is anticipated, and Vicky is forecast to become a remnant low during the next day or two.

Tropicalstormforce winds extend outward up to 105 miles (165 km) from the center.

The estimated minimum central pressure is 1002 mb (29.59 inches).

Vicky is severely sheared by strong upper-level westerly winds. The initial intensity is held at 40 kt based on earlier ASCAT data, but it is entirely possible the cyclone has weakened since this morning and all recent intensity estimates are lower. The shear is the main factor in Vicky's forecast; it is expected to increase substantially (up to 60 kt in 24 h in GFS-SHIPS diagnostics) and should cause the cyclone to weaken. The NHC forecast now shows Vicky becoming a remnant low in 36 hours, and it would not be surprising if it happens sooner than that given the very hostile environment. After Vicky loses all of its convection, the dynamical models suggest that it will take a couple more days for the remnant low to spin down and open into a trough.

Vicky's movement has been somewhat erratic since it formed, but a long-term motion estimate is 325/6 kt. A continued northwestward motion is forecast for the next 12 to 24 hours, followed by a turn toward the west as Vicky weakens and is increasingly steered by low-level easterly winds. The NHC track forecast is based on the TVCN and HCCA consensus aids and is practically on top of the previous forecast.
