FORECAST SUMMARY: Friday, August 31:
*** Forecasts for the 2001 blue mold season will end on August 31 *** Blue mold has been very active this year. Infections have been reported from nearly all growing areas. We will continue to monitor potential transport scenarios, and will report any significant events.
*** An approaching cold front is bringing favorable conditions for disease development to much of the eastern U.S. on Friday *** There is extensive cloudiness and showers west of the Appalachian Mountains. Clouds and the threat of showers will increase along the East Coast as the day progresses. There is HIGH RISK for southern Ontario, the southern Appalachian Mountains, and the entire Ohio Valley region today. There is Moderate Risk for central and eastern NC, southern VA, MD, PA, and southern New England. On Saturday... the front will be through the Northeast, but its western end will lie across the southern mid-Atlantic region. There is Strongly Moderate Risk on Saturday for southern VA, central and eastern NC, and eastern SC. There is Moderate Risk for the southern Appalachian Mountains, with Low Risk elsewhere. On Sunday... the front will be south of most growing regions, but the chance of showers will linger in the mountains. Moderate Risk for the southern Appalachian Mountains on Sunday. Low Risk elsewhere.
*** We strongly encourage growers to monitor their plants for signs of disease. Diligent scouting and prompt reporting of blue mold are essential if one wishes to derive maximum benefit from the services we provide. ***

***** NOTE: These forecasts/outlooks only apply to disease development from airborne transport of spores!!! We do not have the capability to ascertain blue mold development by other means, such as transplanting of infected seedlings, nor will we attempt to do so. Please consult the Extension Service personnel in your area if you have concerns about these matters! *****
