Tropical Storm Irma may have a better ring to it, but do not be lulled by the downgraded status. Winds have slowed to 70 mph, but the storm is still a potent wind machine as it pushes through northern Florida and heads into Georgia today. This is a huge storm! The tropical storm force winds extend 415 miles away from the center.  Flooding has already been an issue around Jacksonville this morning, and severe weather risk extends up the coast to South Carolina today.  Warnings for tornados and flooding will continue to pop up as this rolls farther inland and eventually spins itself out.

We are protected in the Mid Atlantic thanks to blocking High Pressure, but that is enhancing the winds along the coast, which is increasing the storm surge from northerner Florida to Georgia and into the Carolinas. Some of this water will reach the Mid Atlantic, but the track if Irma farther inland will limit that impact north of OBX.

Severe Weather Outlook = Tornado Threat
