ATL: IRMA - Post-Tropical - Discussion

[Extratropical94]

11L IRMA 170909 0000 22.1N 77.2W ATL 140 924

Here we go again!

Could you explain? She was confirmed at 165mph, 140kt is 160mph? Maybe I am confused

She is now at 160 mph. There were a few higher estimates of surface wind, but they decided to go with 160 mph.

NHC went a bit conservative, which is usual with them. When Irma gets stronger they'll update.

[SunnyThoughts]

Will they do a special advisory, or wait till 10 pm for reg, update?

[stormreader]

Look at Irma. WOW! She is intensifying rapidly. What a historic storm!! I have run out of superlatives for this monster!

Now Jax, are about to start getting literary on us, too? lol

[SunnyThoughts]

They found those winds after the 7 update..didn't they.

[Connekto]

A lot of people breathing a sigh of relief here in palm beach gardens... trying to make sure they don't let their guards down..i mean damn not even a day ago se fl was a sure thing now look at tampa scrambling.

[tolakram]

Doesn't seem that particularly dumb to me. The NWS forecast supports his suggestion, at least for his locality, not necessarily whole east coast. Things can obviously change but as things stand now he's probably right.

Agree about the GOES 16. Absolutely incredible.

edited to clarify statement a bit

I don't want to question his local NWS office but perhaps they will revise with the new eyewall size. In addition, saying the east coast dogged a bullet is once again jumping the gun, pun intended Let's see where Irma ends up.

[Extratropical94]

Will they do a special advisory, or wait till 10 pm for reg, update?

Maybe an update at 9 or 10pm EDT and then the regular advisory at 11pm EDT

I've seen some discussion of people suggesting to drain a foot or so of water out of their pool to help prevent flooding from rains.

Have no idea where they got that from though.

Not sure if this is sarcasm or not, but I am actually contemplating doing that (seemed obvious). This will be my first major storm whilst having an in-ground pool some 15 feet from my back doors, so I assumed it would make sense to backwash some water now to avoid overflow (even though I'm aware the paver-deck has a positive slope and drainage). Am I somehow mistaken?

It's a Floridian thing.

Drain your pool by half, throw your pool furniture to the bottom (with weights if need be) and let it ride out. If we get 6+ feet of rain, would a half full or full pool really matter?

Uh, no.

I've done this for years, it works fine. Cheaper to refill the pool than have a wife whining about wet carpeting in the living room.

[meriland29]

You also have to consider she has apparently finished her ERC, is over bathwater temps, AND has the lack of sun fueling her. The sad thing also is that she will have a large portion of nightfall tomorrow before landfall. I am genuinely surprised she is so obviously strengthening now after all that time and effort being a cat 5 for almost 2 days...

Look at these shallow seas along Cuban coast are literally filled with bathtub waters. Well over 31C maxing out the chart.

[Blown Away]

NHC maxed their mid range error rate with Irma and Florida... NHC going to take some heat from public opinion, unfairly...

Before anybody asks like they always do.

Thats about 90 degree water.
