10:30 AM EDT 8/28 (Advisor Forrest)  Despite the central pressure dropping now to 976 mb, maximum sustained winds remain at 70 MPH as of the 8 AM NHC Advisory.  Reconnaissance aircraft recently reported a flight level wind gust of 102 mph. Earlier this morning, a 71 MPH gust was recorded on a Chevron oil platform. The storm has slowed in its forward speed as expected, now moving to the NW at 7 MPH. 

Structurally, Isaac continues to show upper level outflow, a deepening central pressure, yet the central convection fluctuates, most likely due to dry air entrainment. ngthening is forecast, with Isaac likely to become a hurricane today. Tropical Storm winds extend out 205 miles from the center of Isaac. 

This report from August 26 by Meteorologist & Advisor Mike Mogil on Examiner.com two days ago outlined the potential impacts to the region. "Isaac growing and a growing threat to the central Gulf coast."

STORM SURGE:  If the storm comes in at high tide, the water could rise to the following levels in these locations as projected by the National Weather Service:

  • Southeast LA and MS: 6-12 feet
  • Coastal Alabama: 4-8 feet
  • South Central LA: 3-6 feet
  • Florida Panhandle: 3-6 feet
  • Florida West Coast, including Apalachee Bay: 1-3 feet

6:45 AM EDT 8/28 (Forecaster Isaacs & The Tropical Team) Foot's Forecast can report that Forecaster Joey Krastel of our Maryland Team arrived in Biloxi, Mississippi last night and will be leading our on-site reporting of Isaac's arrival along the northern Gulf coast.
