At 900 AM GMT (0900 UTC), the center of Tropical Storm Theta was located near latitude 29.4 North, longitude 34.7 West. Theta is moving toward the eastnortheast near 8 mph (13 km/h), and this general motion is expected to continue for the next several days. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Slow weakening is forecast during the next 48 hours. Tropicalstormforce winds extend outward up to 205 miles (335 km) from the center. The estimated minimum central pressure is 989 mb (29.21 inches).

ction associated with Theta has decreased further this morning, with strong southwesterly shear displacing the remaining convection to the north of the center. Based on the decreased organization, the initial intensity is lowered slightly to 55 kt. Theta has continued to slow its forward speed, with the initial motion now 075/7. The cyclone is being steered by the southern part of the mid-latitude westerlies to the north of a mid-level ridge, and this general motion should continue for the next 72 h or so. After that time, the global models suggest that the cyclone should shear apart, with the remnant low-level circulation moving northeastward on the southeast side of a deep-layer cyclone over the northeastern Atlantic. There has been little change in the guidance since the previous advisory, and the new official forecast track is similar to the previous track. While the cyclone is currently experiencing strong shear, the global models show that this might diminish somewhat during the next 72 h as Theta moves into an area of light winds near an upper-level trough axis. This, combined with sufficient instability for deep convection, should allow the storm to change little in strength during this time. After 72 h, strong mid- to upper-level northerly flow should cause the system to weaken as the convection dissipates and the upper-level portion of the storm is pushed off to the south. The new intensity forecast is lowered a bit from the previous forecast, and it lies in the middle of the intensity guidance envelope.
