*** Disease Update - 26 June *** From NC..... Tom Melton informs us that disease activity has recently been observed in the following counties: Beaufort, Pitt, Nash, Warren and Wake. These recent discoveries are in irrigated fields (Pitt and Warren), in shady areas, or in coastal areas that have recently had some rain (Beaufort). The original areas of blue mold outbreaks in north-central and northeast NC have been very dry. Blue mold is not progressing in those areas. In PA..... Bob Anderson reports new outbreaks in Lancaster County. One serious outbreak is in a 5-acre field. Transplants were moved to this field during a recent 2-week period. Nearly all plants are showing symptoms and systemic infection is present. He also states that calls are coming in from many areas in Lancaster County.
FORECAST SUMMARY: Wednesday, June 26:
***** Showery weather is expected over the eastern U.S. Wednesday and Thursday. ***** Trajectories from most sources will be moving northeast. With the weather features changing little from Wednesday to Thursday, transport events will affect the same areas for two days in a row. Conditions will range from mixed in the mid-Atlantic states to favorable in the Northeast and Southeast. Beginning in the Northeast..... there is Strongly Moderate Risk for southeast PA, Moderate Risk for southern New England. In the mid-Atlantic...... trajectories from the source in northeast TN move to the east. There is Moderate Risk for northeast TN, northwest NC, and southwest and south-central VA.
