Thursday Evening July 9 2020

Tropical Storm Fay has officially formed today. The winds are a minimal 40 mph and it is nor well organized. The heaviest rain is well Northeast of the center of circulation. That will change overnight as the winds should pull that heavy rain on to Delmarva bringing Ocean City and the Delaware beaches a few inches of rain.

This is behave like a strong Nor’easter, mostly in the morning. It will be stormy at the beaches. This is a small storm, so parts of our region inland may hardly notice much of a difference.

The National Hurricane Center has identified the Low at 8 PM about 70 miles northeast of Cape Hatteras, NC.  They have chosen the follow a track a little farther east, but the models I will show in comparison still bring the center of the storm onshore near Ocean City.  The only reason that matters will be how far inland the rain will reach.

All of these models agree in an average of over 2 inches of rain in eastern Delmarva. There is potential for some spots to reach 4 inches or more near the coast.
How far west the rain reaches will depend on the track of the Low.  There will be a sharp cut off somewhere near the Bay.

Water Impact
The winds will be onshore for the beaches, but FROM the north on the Bay. This will help water drain out and may end up quite low (not flooding)
