winds of 175 mph (280 km/h) with higher gusts. A special advisory
will be issued at 800 AM AST (1200 UTC) in lieu of the scheduled
intermediate advisory for Irma.

Does the upgrade to Cat 5 impact how quickly or at what angle Irma can change direction?
And NWS sounds like she will miss the "hurricane shredders" or is it too soon for certainty?
Yeah, good reminder, I'm having a hard time believing a sharp right turn north at this strength. But I assume it will be weaker by time it gets to Cuba. Last thing we want is for a powerhouse to slow down or stall. That's never good. If it misses the "shredders" I'm not sure there's anything to weaken it less than a Cat 4 or 3 until it hits the U.S.
Sometimes that turn it makes disorganizes its structure and weakens it a bit so maybe that might help before it hits land.
National Hurricane Center now has it a Cat 5 all the way to Cuba. Dear Lord!
8am Update: See link for Rainfall, Surge, Winds, Watches and Warnings Info.
Still maintaining a 14mph speed.

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 800 AM AST (1200 UTC), the distinct eye center of Hurricane Irma
was located near latitude 16.7 North, longitude 57.7 West. Irma is
moving toward the west near 14 mph (22 km/h), and this general
motion is expected to continue today, followed by a turn toward the
west-northwest tonight. On the forecast track, the dangerous core of
Irma will move near or over portions of the northern Leeward Islands
tonight and early Wednesday.
Reports from NOAA and U.S. Air Force Hurricane Hunter aircraft
indicate Irma continues to strengthen and maximum sustained winds
have increased to near 175 mph (280 km/h) with higher gusts. Irma
is an extremely dangerous category 5 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some fluctuations in intensity are likely during the next day or two, but Irma is forecast to remain a powerful category 4 or 5 hurricane during the next couple of days.
Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 140 miles
(220 km).
The latest estimated minimum central pressure from aircraft data is
929 mb (27.44 inches).
