At 300 PM GMT (1500 UTC), the center of Tropical Storm Wanda was located near latitude 40.6 North, longitude 37.8 West. Wanda is moving toward the south southeast near 8 mph (13 km/h). A southward motion is expected this afternoon through Saturday, and a turn toward the northeast is expected Saturday night or Sunday. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Little change in strength is expected today and tonight, while slight strengthening is possible on Saturday. Wanda is expected to become an extratropical cyclone in a few days. Tropical storm force winds extend outward up to 125 miles (205 km) from the center. The estimated minimum central pressure is 994 mb (29.36 inches).

Wanda's cloud pattern has again changed little since the last advisory, with bands of moderately deep convection currently located mainly in the southern semicircle. Just-received ASCAT data indicates an area of 40-45 kt winds mainly west of the center, and based on this the initial intensity is a possibly conservative 45 kt. The ASCAT data also show that the wind field has expanded on the west side, and the initial and forecast wind radii have thus been modified.

The initial motion is now south-southeastward or 160/7 kt. A southward motion is forecast during the next 24 h as a mid-level ridge builds to the north and west of the cyclone. After that time, a developing mid-latitude cyclone currently south of eastern Canada will move close enough to break down the ridge and produce southwesterly deep-layer flow around Wanda. This should cause the tropical cyclone to turn northeastward and accelerate, with a quick northeastward motion continuing until Wanda dissipates. The latest track guidance is in good agreement, and the new forecast track lies close to the various consensus models.

The southward motion should bring the center over slightly warmer water during the next 24-36 h, and during this time Wanda should be in an area of light to moderate shear inside of the circulation of a nearby upper-level low. This environment should allow Wanda to maintain its strength and perhaps strengthen a little. By 48 h, the mid- latitude system approaching from the west should cause increased shear, although the associated increased upper-level divergence may offset any weakening caused by the shear. Wanda is forecast to merge with a frontal zone by 72 h, and by 120 h the system is forecast to weaken to a tough to the south of a large mid-latitude low over the northeastern Atlantic. The new intensity forecast has only minor adjustments from the previous forecast.
