Heavy Rainfall Threat Increasing

work

The location of the heaviest rainfall will likely be different than this model run (See below), but very heavy rainfall threat is increasing for the next 72 hours. A Flash Flood Watch is posted for much of Virginia and it may be expanded to Delmarva soon, especially if overnight model runs continue to show very heavy rainfall. Atlantic ocean temps off the U.S. East Coast are at record levels and this will increase the moisture available to this storm system.
