*** Epidemic Update - 22 September: New report from NH. CDM has been confirmed in Rockingham County, NH. Please view the Epidemic History for details. ***


Regional Weather: Eastern North America

Dry weather overall; rain in the Plains; showers from Maria in the East? The weather pattern is stagnant with high pressure ruling eastern North America and fronts in the Plains / upper Midwest / southern Canada. Suuny to partly cloudy skies and dry weather are dominant. Hurricane Maria, moving north off the Southeast coast, will introduce some clouds, showers, and wind to the mid-Atlantic coast. The front in the Plains has plenty of rain associated with it as it inches eastward.



Overview: Epidemic spread unlikely most regions. The favorable conditions in the Plains states should have little impact on the early-week transport events. Most events are benign. Some epidemic spread is possible in parts of the South, and along the mid-Atlantic coast (mainly on Tuesday).
