Tuesday August 4 2020
Tropical Storm Isaias still had top winds of 70 mph at 5 AM. The storm is moving faster to the North-Northeast at 28 mph. That means the worst conditions arrived a few hours sooner, but it will end sooner as well. The worst conditions are now expected to be between 7 AM ad 1 PM.
A Tornado Watch is in place until noon including Baltimore, Annapolis, and across the Bay to Delmarva. We have already had warnings issues and more on the way.
Small EF-0 and EF-1 tornados are coming with tropical systems. These will likely be rain wrapped and hidden, but locally can push winds close to 100 mph in their path.
⚠️When rotations is spotted on Doppler Radar, a WARNING will be issued for that area.
A Flash Flood Watch is still in place, and some warnings have been issued. More is on the way with rainfall totals still expected between 3 and 6 inches.
This post has the latest conditions, radar and satellite loops, and forecast highlight. Please check back as I will be adding simulation timelines for rain and wind next.
