Tropical depression 9 will be tropical storm Imelda soon. It will move north through the Bahamas and east of the Florida east coast through the weekend. Heavy rainfall and tropical storm force wind gusts can be expected. Forecast models are showing that Imelda will become a hurricane as is moves north, and stall east of the Georgia / South Carolina coast as it interacts with a powerful hurricane Humberto further east. It is then forecast to resume an eastward track east into the Atlantic early next week.

Residents of the SE US coast, especially from eastern Florida north to North Carolina should follow this tropical cyclone and make appropriate preparations.

Thursday Morning Update

Imelda Bermuda summary
Imelda passed over Bermuda Thursday night / Friday morning close to midnight. Official maximum sustained winds were estimated at 100 mph, then dropped to 90 mph close to landfall. From the data below, it appears that this was a significant overestimation. It's possible that the very strongest winds were not sampled, but maximum wind should have been close as what was left of the eyewall passed over the islands. Official winds of 90 mph should have at least produced gusts to 20% above this and many times considerably higher.
