29 August 2000 Downy Mildew Forecasts

 

FORECAST DISCUSSION: Tuesday, August 29:

*** Our apologies for the late posting of Tuesday's forecasts. Network difficulties (the apparent cause of the problem) at the Forecast Center have been rectified and we hope there are no further delays.

*** Epidemic Update - 29 August: A serious outbreak of Downy Mildew has been discovered on summer squash near the border of Duplin and Wayne counties in eastern NC. These counties border Sampson County, site of the previously known outbreak. Given the proximity of the known disease locations, the launch site for the eastern NC sources has been changed to Mount Olive, NC, which is more centrally positioned amid Duplin, Wayne, and Sampson counties.

 *** Complex, unsettled weather pattern evolving in the Southeast and mid-Atlantic regions. *** Elements of weather at the surface and the upper levels are combining to produce a period of cloudy, showery weather for the next several days. The focus for heaviest rains will initially be near the coast, but moving inland later in the week. The Carolinas appear to be the targets for the greatest rainfall. Meanwhile, drought conditions continue in the TX/OK region. On Tuesday... there is Strongly Moderate Risk for growers in east-central and southeast NC and south-central SC, Weakly Moderate Risk for north-central SC. Florida growers are at Moderate Risk, while southern GA, southwest NC, and OK growers are at Low Risk. On Wednesday... HIGH RISK for eastern and south-central NC; Moderate Risk for southwest NC, northwest SC, and northeast and east-central GA. Florida growers will again be at Moderate Risk. Low Risk for southern GA and OK.
