  1. Update on Tropical Storm Lee 3:30 pm – September 3, 2011

  2. Key Points • Tropical Storm Lee has strengthened over the last 24 hours, and is now a strong tropical storm with maximum sustained winds of 60 mph over water east of the center. • The system is embedded in weak steering currents, and will move slowly and erratically toward the N and NE later this weekend. • On the track, widespread very heavy rainfall of 6-12” (locally heavier in spots) will be the major threat. • Gusty winds (a few gusts of 40-45 mph possible) will also cause some issues, with a few power outages possible. • Risk for a few tornadoes looks like it may be greater than initially expected, particularly along/SE of the Natchez Trace.
