Regional Weather: Southeast / mid-Atlantic U.S.

Hot and mostly dry. The strong Bermuda High is in charge of the weather this week, producing a hot and humid environment. It will be dry to start the work-week with the chance of showers on the upswing as the week progresses. Highs well into the 90s, lows only in the 70s.

 

OUTLOOK:

Overview: Epidemic spread unlikely. The spring growing season is almost completely done in central and southern FL and is coming to a close in northern FL and southern GA. This reduces inoculum levels coming out of those sources. Recent weather in the Carolinas / southeast VA has been dry around nearly all the sources, also hindering spore production. Conditions during the transport events range from unfavorable to mixed as any airborne spores move near-source, east, or northeast.

Risk prediction map for Day 1: Monday, July 1

Low Risk in southeast AL, southwest GA, the eastern FL panhandle, and all but the far northern FL peninsula. Minimal Risk to cucurbits elsewhere.

Risk prediction map for Day 2: Tuesday, July 2

Low risk for southeast AL, southern GA, and FL except the western panhandle. Minimal Risk to cucurbits otherwise.

Risk prediction map for Day 3: Wednesday, July 3

Low risk for FL except the western panhandle, southeast AL, southern GA, southern and eastern SC, eastern NC, southeast VA, eastern MD, and DE. Minimal Risk to cucurbits otherwise.
