UPDATE #4: Now Cat 2, crossed the coast, winds 105 mph (165 km/h) and 942 mb. Slowing down, but hurricane force winds are still covering an area 80 miles from the eye. Hurricane Jose is Cat 3, 120 mph, 956 hPa. Moving at 14 mph.
UPDATE #3: Late Sunday night Australia time (Sunday morning US 11AM) Official advisory updates are here. #46 says 130mph, with lowest pressure 933 hPA . Watch news come in on twitter #IRMA. Blackouts across Miami — over 1 million without power. Storm surges. Streets turning into rivers. Waterspouts off the east coast of Florida.
UPDATE#2: Sunday morning Australia time. Irma now
a Cat 3, up to a Cat 4 again, savaging Cuba and weakening as it loses moisture being half over land. It is already affecting Florida, with gusts of 50-60 miles per hour, and set to go north right along the western edge of the peninsula (which has caught people off guard, as the eastern edge have boarded up windows in anticipation, but many on the western side did not). In the 12 full hours over the ocean north of Cuba it may well recover a lot of wind speed quickly. Will hit the Keys in 12 hours. Watch the windy.com radar here, or the Ventuski radar and the TropicalTidbits updates here. Weatherbell forecaster Joe Bastardi has a public update with the eye track running along the west edge of Florida. He is expecting it to speed up and hit near Port Charlotte as close to a Cat 5 with 150 mile per hour winds. He predicts it to deepen from 935hPa to 896hPa. Hurricane Jose is following in the wake of Irma and could be a big problem. Watch his public video (top right at his site). He points out the high pressures in the North Atlantic are also helping to drive a bad hurricane season.
Best wishes to the people of Florida, Cuba, the Caribbean.

Thoughts also to those in Mexico with the Magnitude 8.1 Earthquake hitting the southern coast, and at least 61 dead.
