Folks it's tracked east of NHC path Dade and Broward experiencing 100mph...

KMIA reporting peak wind/ gust at 64 knots , here in south Miami seems about right. Few tree limbs down , no power.
Where are you seeing 100 mph in Dade. ?

[KBBOCA]

Wow... Miami flooding already? High tide not until 12:50, I think...

KMIA reporting peak wind/ gust at 64 knots , here in south Miami seems about right. Few tree limbs down , no power.
Where are you seeing 100 mph in Dade. ?

By the beaches.

By the way, that 64 knot reading was an hour ago, since then it stopped reporting wind measurements.

Eyewall replacement cycle may have inner eye bouncing around newer larger eye. 20 miles east of NHC forecast. Big difference for MIA/FLL!

University of Miami's marine campus on Key Biscayne reported 100 mph some time ago. MIA has reported 97 mph wind gusts as well.

Cudjoe Key means Irma is 20 mi. east of NHC forecast. It's *not* turning NE but that small distance enough to increase impact in metro area.

Looks like the Miami River, on the southern end of downtown/north of Brickell.

Key West Radar down?

Looks like the Key West radar went down...last update was over 20 minutes ago. #Irma

What is going on with the dry spot under the eyewall? Is this the start of a massive eyewall ?

[AutoPenalti]

Its hitting that ridge of high CAPE air I mentioned yesterday.
Can't get a reading now due to cloud cover.
Also, looks like a Theta-E ridge may be building between Irma and Tampa this afternoon.
Keeping an eye on this.

Looks like it already is, its strengthening some more.

Wow, Metar says peak 63 knots , where are you getting that report.

[NDG]

Between the last two recon fixes it moved a little east of due north.

This is already 1 hour+ old

Franklin County issuing evacuation orders. How many counties have issued evacs? It seems all of FL could be getting hit hard...

Am I imagining things or is there lots,of dry air intrusion into Irma?

Indeed, she has been moving east of her projected 11PM and 5AM NHC paths. Is the further east track of the Ukmet vs the other 3 major models at 0Z or at least the somewhat more east 0Z GFS going to end up with a win? I'm now leaning toward the 0Z Euro verifying too far west and Irma making actual landfall somewhere in SW FL as opposed to the runs that had her only skirting the SW coast.This also means a harder hit on SE FL and further up FL. Anyone else's opinion about this and how she has been moving?
