Very destructive 145mph hurricane heading for the US Gulf coast.
Landfall expected in the next 5-7 hours near Pensacola.
Tremendous storm surge will completely overwash the barrier islands.
If you are still within the storm surge zones, YOU MUST LEAVE NOW. There is going to be tremendous destruction on the barrier islands.
Recon. reports the pressure is now down to 932mb and continues to fall as Dennis is now a strong category 4 hurricane capable of extreme to catastrophic damage. Dennis will make landfall as a powerful category 4 hurricane much stronger than Hurricane Ivan.
Buoys in the northern Gulf are recording wave heights of 25-35 feet and wave action of 20 feet + is going to be arriving on the barrier islands shortly.
Storm Surge:
A devastating surge is expected near and to the right of where the center crosses the coast. Gulf surge heights of 15-19 feet can be expected NOT including wave heights. The beach front and barrier islands will sustain catastrophic surge damage and massive beach erosion. Surge will be highest from Fort Walton Beach west through Pensacola to Gulf Shores AL. Surge at the head of Pensacola Bay may exceed 18-23 feet. Areas flooded by storm surge from Hurricane Ivan will experience surge values 4-6 feet higher with Dennis.
Wind:
Dennis is an extremely dangerous category 4 hurricane, roughly 5-10 times stronger than Ivan. 145mph sustained winds are confined to the eyewall region with hurricane force winds extending outward about 50 miles from the center and TS force winds 230 miles from the center. Tropical storm force winds are already occurring along the coast and will quickly build to hurricane force in the next 2-3 hours. Extreme winds will arrive with the eyewall around 300-500pm today. Few structures in the eyewall will survive the sustained 145mph winds with gust easily over 170mph. Hurricane force winds will extend far inland (150-175 miles) due to the fast forward motion.
Rainfall:
Dennis will begin to slow as he moves inland over the next 36 hours. Rainfall amounts of 4-8 inches will occur with isolated 12 inches amount possible. Flooding threat greatly increases Tues and Wed. as Dennis slows over the Tenn. Valley. Rainfall amounts could exceed 20 inches in some parts of the SE this week.
