At 300 PM GMT (1500 UTC), the center of Tropical Storm Wanda was located near latitude 41.9 North, longitude 39.6 West. Wanda is moving toward the north near 6 mph (9 km/h). A slow eastward motion is forecast by tonight, followed by a faster south southeastward to southward motion by Friday and Friday night. Recent satellite wind data indicate that maximum sustained winds are now near 45 mph (75 km/h) with higher gusts. Little change in strength is expected through Friday, with some slow strengthening expected Friday night and Saturday. Tropical storm force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 994 mb (29.36 inches).

Wanda continues to maintain bands of moderately deep convection near the center, and the cyclone continues to display anticyclonic outflow. However, cold air clouds are wrapping around the southern side of the circulation, and in the big picture Wanda appears to be embedded in a larger-scale baroclinic low. A recent ASCAT-A overpass suggests that the maximum winds are now near 40 kt, which is between the satellite intensity estimates from TAFB and SAB.

The initial motion is northward or 000/5 kt. During the next couple of days, a narrow mid-latitude ridge is forecast to build to the northwest of the cyclone, which should cause Wanda to turn southeastward and southward by the 48 h point. By 60-72 h, another mid-latitude trough approaching Wanda should finally cause the system to begin to accelerate northeastward, with this motion persisting through the end of the forecast period. The new guidance shows a little more southward motion by 48 h than the previous guidance, and the new forecast track is adjusted a little southward near that time.

Little change in strength is likely during the next 24 h as Wanda remains over sea surface temperatures of near 20C. By 48 h, the southward motion brings the center over slightly warmer water, and some modest strengthening is possible by that time. Many of the guidance models show more strengthening and a higher intensity than the official forecast between 48-72 h, and some adjustment may be needed to that part of the forecast in later advisories if this trend persists. By 96 h, Wanda is expected to merge with a frontal system and become extratropical over the northeastern Atlantic.
