The National Weather Service (NWS) continues working on post storm surveys for the severe weather that tore through the Washington, D.C. and Baltimore areas on June 1. So far, it has confirmed 10 tornadoes touched down, all in Maryland.
Of the 9 tornadoes, 6 were of the weakest variety - rated a 0 (winds to 65 to 85 mph) on the Enhanced Fujita (EF) scale - which ranges from 0 to 5. Three of the tornadoes were rated EF-1 (with winds estimated at 86 to 110 mph):
* in the Watersville area of Howard county
* in the Pleasant Hills area of Harford county near Fallston and Bel Air, where two injuries were reported
* near Gamber in Carroll county
