Aerial recon has found hurricane force wind near the rapidly developing eye of Isaac. The storm is a hurricane as of 1620 UTC on Tuesday. Forecast track still comes uncomfortably close to New Orleans, though this storm is more of a rain and wind event than one of catastrophic storm surge. Still, surge of 6-12 feet is expected, so those in mandatory evacuation areas have been urged by authorities to leave.
