What Has Changed
Freeze Warnings and Frost Advisories issued for tonight through Saturday morning.

2. Frost and freeze impacts likely tonight and Saturday night where the growing season continues.
Discussion
KEY MESSAGE 1...Elevated tide cycles persist due to Post- Tropical Cyclone Josephine well off the coast, resulting in widespread minor coastal flooding continuing in Ocean County, NJ and Sussex County, DE.
As Post-Tropical Cyclone Josephine lingers well off the coast elevated tide cycles are persisting some areas.
In Ocean County, New Jersey and Sussex County, Delaware, water levels remain elevated and minor tidal flooding is continuing, particularly in the back bays. In fact a few locations in the back bays came very close to or even touched moderate levels of coastal flooding yesterday with the high tide. It's going to take some time for water levels to diminish in these areas so we've continued the Coastal Flood Advisory for these counties through this evening. Elsewhere along the Atlantic coast and Delaware Bay any additional coastal flooding looks to be spotty at most.
At this time we are not forecasting any coastal flooding for the Maryland eastern shore.
KEY MESSAGE 2...Frost and freeze impacts likely tonight and Saturday night where the growing season continues.
A Freeze Warning was issued for areas north and west of the I-95 corridor from midnight until 9AM Saturday where the growing season remains active. For the I-95 corridor and areas south and east, a Frost Advisory was issued from midnight until 9AM Saturday for all other zones, excluding Cape May County in New Jersey, Sussex County in Delaware, and the coastal strip in both states.
