The track has shifted a bit from earlier when tampaedski posted his check-in and it is looking to hit FL Big Bend Region very hard with both Cat 4 winds and storm surge. I saw an update on MSNBC during the 11th Hour and it is looking like people have heeded the evacuation warnings pretty well. The reporter was in Perry and pointing out the boarded up restaurants and bars noting that it was pretty much a “ghost town”. I hope the same is true all along that coastal area.

Here are some stats from the 11pm update:

STORM SURGE: The combination of a dangerous storm surge and the

tide will cause normally dry areas near the coast to be flooded by

rising waters moving inland from the shoreline. The water could

reach the following heights above ground somewhere in the indicated

areas if the peak surge occurs at the time of high tide... Wakulla/Jefferson County line, FL to Yankeetown, FL...12-16 ft

Ochlockonee River, FL to Wakulla/Jefferson County line, FL...8-12 ft

Yankeetown to Chassahowitzka, FL...7-11 ft

Chassahowitzka, FL to Anclote River, FL...6-9 ft

Carrabelle, FL to Ochlockonee River, FL...5-8 ft

Anclote River, FL to Middle of Longboat Key, FL...4-6 ft

Tampa Bay...4-6 ft

Middle of Longboat Key, FL to Englewood, FL...3-5 ft

Indian Pass, FL to Carrabelle, FL...3-5 ft

Englewood, FL to Bonita Beach, FL...2-4 ft

Charlotte Harbor...2-4 ft

Mouth of the St. Mary's River to South Santee, SC...2-4 ft

Beaufort Inlet to Drum Inlet, NC...2-4 ft

Pamlico and Neuse Rivers...2-4 ft

South of Bonita Beach to Chokoloskee, FL...1-3 ft

South Santee, SC to Beaufort Inlet, NC...1-3 ft

Drum Inlet to Duck, NC...1-3 ft

Chokoloskee, FL to East Cape Sable, FL...1-3 ft

Flagler/Volusia County Line, FL to Mouth of St. Mary's River...1-3

ft

Indian Pass to Mexico Beach...1 to 3 ft

Florida Keys...1-2 ft The deepest water will occur along the immediate coast in areas of

onshore winds, where the surge will be accompanied by large and

dangerous waves. Surge-related flooding depends on the relative

timing of the surge and the tidal cycle, and can vary greatly over

short distances. For information specific to your area, please see

products issued by your local National Weather Service forecast

office. WIND: Hurricane conditions are expected within the hurricane

warning area in Florida early Wednesday morning, with tropical

storm conditions beginning within the next few hours. Tropical storm conditions will begin within the tropical storm

warning area along the Florida Gulf coast and the Florida west coast

soon. Hurricane conditions are possible within the hurricane watch area

along the coasts of Georgia and South Carolina Wednesday and

Wednesday night. Tropical storm conditions are expected to begin on Wednesday in the

warning area along the east coast of Florida, Georgia, and South

Carolina, and spread into North Carolina Wednesday night and

Thursday. Tropical storm conditions are possible within the watch

area in North Carolina by Thursday. RAINFALL: Idalia is expected to produce a swath of 4 to 8 inches of

rainfall with isolated maxima up to 12 inches from the Florida Big

Bend through central Georgia and South Carolina, and through eastern

North Carolina into Thursday. These rainfall amounts will lead to

areas of flash, urban, and moderate river flooding, with locally

considerable impacts. SURF: Swells generated by Idalia are affecting the southwestern

coast of Florida and will spread northward and westward to the

north-central Gulf coast through Wednesday. These swells are

likely to cause life-threatening surf and rip current conditions.

Please consult products from your local weather office. TORNADOES: A few tornadoes are possible tonight from the coast of

west-central Florida northward into the Florida Big Bend region.

The tornado risk will shift into southeast Georgia and the coastal

Carolinas on Wednesday. NEXT ADVISORY

-------------

Next intermediate advisory at 200 AM EDT.

Next complete advisory at 500 AM EDT. $$
