MIAMI - Residents in parts of the Miami metro area are under mandatory orders to leave their homes Thursday morning as Hurricane Irma barrels toward the region with potentially catastrophic winds.
During several media appearances Wednesday, Florida Gov. Rick Scott strongly urged people to evacuate if asked to do so by local officials. The governor waived tolls on all Florida highways and told people if they were thinking about leaving to "get out now."
watch this aerial video from this Caribbean Island. The hotel and structures are still there even with 130mph+ winds and rain and water surge but looks like windows are blown out and some parts of building ripped off. Palms too.
Im sure they built to withstand hurricanes but not Cat 4-5?
Also.. this shows you can ride it out in a sturdy structure if you dont get flooded but... don't expect to wake up next day and go to a Dunkin donuts or get gas anywhere. You'll be isolated for who knows how long.
You dont have to evacuate far from the center (70 miles is enough) but question is where exactly will that center be!
With the current track can anyone tell me what the predicted impact would be for Sarasota, FL?
Winds and storm surge? Rain? Would it be like a cat 3 or cat 2?
I really haven't seen any info on what the outlying areas will experience 50-100-150- miles out from the eye, especially since right now it is traveling over small islands.
Storm Surge:
Overall, the main/big Storm surge will be right around the eye/center(eyewall) of the storm and points a few miles north/northeast of that and slowly getting smaller the further you are from the storm center. So if the storm went up E coast of FL then Sarasota would only have some fairly minor surge potential, and that would just be from the continued multi day wind pushing water on shore some but not nearly like the eye would. Winds in a hurricane in Northern Hemisphere rotate counter clockwise around the center so first winds in Sarasota as storm nears S tip of FL would be pushing water more towards the Gulf of Mexico or to the SW and as the storm goes up the E coast of FL (assuming it does that track) then your winds would shift in relation to the center so as center passes to your east winds would be more likely to push water in a more North to South direction potentially casuing trouble in Southern areas of Sarasota Bay, and as storm heads north winds would push water more East direction. So minor surge just from continued good breezes minimum may cause some headaches depending on elevation. The closer the storm center gets the worse the potential as winds are strongest nesr the eye and less as you go out from that point.
A Worst case for Sarasota surge wise would be if the storm cut between S FL tip and Cuba and then center came up to Sarasota as that would be worst side of storm for surge.
Wind:
The "good" news in a well built / healthy Cat4/5 like Irma is that those crazy wind speeds are only in the eyewall that surrounds the center/eye and become much less as ou head out from the center. As a strong hurricane weakens with land interaction/landfall those winds come down in speed but also start to spread out by several miles. Currently, Irma has Hurricane force winds (74mph or greater) extending 50 miles from the center and Tropical Storm force (anything from 34-73mph being stronger the closer you are to the center) extend 185miles from the center. So how ever far you are from the center determines your winds, which will typically be found in rain bands where the storms are able to bring those winds down to the surface more easily.

[quote=SkyNSea55;49444542]Here in Charleston. Feel we must leave. But where and when to go? North or West and how far? The cone is so long and wide. Help from experienced storm watchers much appreciated. We live 4 miles from Isle of Palms Beach on the mainland. Hoping for the best but planning for the worst.[/QUOT
I would say up I95 to 40 to Raleigh where we are. From models storm will be west of here toward Charlotte and Ashville. East of here starts to be pretty low country.
Having to stay put here in North Port, SW Fl. We have 3 shelters within 10 minutes and they are pet friendly but will not take Exotic Pets. Out of 5 animals, the cat is the only non-exotic. Hopefully we will be alright. Our house is the highest on the street and the water from Charley didn't get up to the house. The canal in back was a bit higher but still didn't come in.
Stay safe everyone. Pray for the best!
