From Accuweather.com's hurricane center:
1. As of 11 a.m. EDT, Tropical Depression Lee was located near 31.9 north and 51.5 west, or about 780 miles east of Bermuda. The depression has moved little over the past 6 hours. It has sustained winds of 35 mph. Estimated central pressure is 1010 millibars or 29.83 inches.
2. Elsewhere in the tropics, a tropical low was located near 17 north and 43 west and was moving west-northwest at 10 knots. Despite plenty of shear from an upper trough of low pressure just to the west of this feature, it has maintained a low-level circulation and convection close to the center of circulation. Some models back the upper-level trough away from the low-level center Friday into Saturday providing a better environment for development.
3. A tropical wave is along 81 west south of 20 north, moving west at 10 knots. A second wave is near 10 north and 24 west, moving west around 10 knots.
4. An upper trough of low pressure south of Bermuda will build southwest toward the Bahamas and may have to be watched for slow tropical development over the weekend. (DK note, this is where Katrina formed)
