Randy my understanding is that this is a fast mover at least compared to Harvey, correct?
That should at least reduce flooding due to rainfall alone but my understanding is also that the storm surge could cause catastrophic flooding in South Florida depending on where it hits simply because of how powerful the storm is and how low in elevation much of the Florida coast is.
I'll be paying close attention and will be evacuating Tampa if/when it is necessary. It might not be necessary depending on its track but either way I'm picking up some batteries, bug spray, water, and the most delicious canned foods and cookies I can find.
Harvey set a new standard in slow. Actually, from a respected poster i follow on american weather, don't expect Irma to be very fast as it churns northward between the trough and ridge... be it on land or water. A storms <fast> forward speed also causes increased wind damage.
Surface winds just seen are extremely high, and Irma's headed to warm waters/more energy. Wow 196mph at flight level.
I am sure shores / flat areas prone to flooding etc will be as usual, but the wind field is quite vast and suspect the winds will do more severe damage than water (total guess).
Living on the coast of FLA, maybe a good plan is to book a refundable hotel that will give you an out. If you are in a high rise with safe parking for the car, I would likely ride it out. Otherwise, a good plan is to book somewhere you could get to late in the game (opposite coast, north or south), in addition to loading up on supplies.
I highly recommend (TO EVERYONE) a cheap LED lantern for area lighting. Get
this one for $8 and or
this one. On low I think they can run for 2 weeks straight. Also, a tiny clip-on (to a hat) LED light for hands free duty. Just say no to candles, which are far too dangerous in the era of cheap LED lighting. I have seen lit wicks riding in molten wax on that little piece of aluminum after glass candle holders have broken.
In the era of mobile phones are our lives, I also recommend a
small solar panel to be able to charge your phone, instead of depending on your car. One that could hang out a window if needed and has a battery inside, which you connect to via USB. Solar has evolved a lot, and works even on cloudy days.
The more panels to unfold, the better
