1st-8th…Topical Storm Andrea’s interaction with a cold front led to heavy rain in the
East, with 4 inches or more falling in portions of the Atlantic Coast States from Florida to Massachusetts. Andrea made landfall during the late afternoon of June 6 in Dixie County, FL, with maximum sustained winds near 65 mph. Most of Andrea’s impacts were related to heavy rain, although weakening and acceleration after landfall helped to limit flooding.
Rain also provided much needed moisture for drought-stressed rangeland, pastures, and emerging Summer crops in the Southern Plains.

Andrea’s tropical moisture blended with frontal and jet stream energy to produce significant rainfall in the East.
