CUCURBIT DOWNY MILDEW ipmPIPE

 

Cucurbit Downy Mildew Forecasts - Friday, March 24, 2017
 

*** Epidemic Update - 8 March: First reports from FL. CDM has been confirmed in Citrus County and Miami-Dade County, FL. Please view the Epidemic History for details. ***

 

Regional Weather: lower Southeast U.S.

Mostly dry; showers possible some areas. High pressure off the coast is the main influence on the weather. A frontal system moving across the southern U.S. will cause some showers in the mainland sections Saturday and Sunday. A few showers are possible in parts of FL with the onshore flow. Highs in the 70s to lower 80s, lows in the 50s and 60s.

 

OUTLOOK:

Overview: Epidemic spread possible. The more noteworthy transport events come out of north-central FL. Events are moving generally northwest each day. No rain is expected near the source. Skies during transport are mostly sunny today, but will be more partly cloudy Saturday and Sunday, allowing for more survival of airborne spores those days. Washout is possible over some mainland areas during those events. The risk to any available host plants is not substantial but is definitely above minimal. Localized disease development is possible in southern FL each day.
