11 AM Tuesday August 4

Tropical Storm Isaias is moving faster this morning and as we discussed before, will be moving through sooner.  At of 11 AM, sustained winds were still 70 mph, with tropical storm force winds reaching 140 miles from the center.  Needless to say, the Tropical Storm Warning and Tornado Watch remain in effect.

The location was within 20 miles of Fredericktown, Maryland. The forward speed was 35 mph to the North Northeast.
