Irma: a record-breaking hurricane.
Irma is an extremely impressive hurricane in both infrared and
visible satellite images. Experimental GOES-16 one-minute visible satellite pictures show a distinct 25-30 n mi wide eye with several mesovortices rotating within with eye. The aircraft have not sampled the northeastern eyewall where the strongest winds were measured shortly before 1200 UTC this morning, but the Air Force plane will be entering the eye in that quadrant momentarily. A peak SFMR wind of 154 kt was reported, with a few others of 149-150 kt. Based on these data the initial intensity is set at 155 kt for this advisory. This makes Irma the strongest hurricane in the Atlantic basin outside of the Caribbean Sea and Gulf of Mexico in the NHC records.

Irma is a potentially catastrophic category 5 hurricane and will bring life-threatening wind, storm surge, and rainfall hazards to portions of the northeastern Leeward Islands tonight and tomorrow. These hazards will spread into the Virgin Islands and Puerto Rico tomorrow. Preparations should be rushed to completion before the arrival of tropical-storm force winds tomorrow morning in Virgin Islands and Puerto Rico. Lets hope the Clignons aren't tempted there. |

Information straight from the horse's mouth: http://www.nhc.noaa.gov/text/refresh.../060235.shtml? http://www.nhc.noaa.gov/text/refresh.../060236.shtml? http://www.nhc.noaa.gov/text/refresh.../060234.shtml? Extracts: SUMMARY OF 1100 PM AST...0300 UTC...INFORMATION [September 5th/6th] ----------------------------------------------- LOCATION...17.4N 61.1W ABOUT 50 MI...80 KM ENE OF ANTIGUA ABOUT 50 MI...75 KM ESE OF BARBUDA MAXIMUM SUSTAINED WINDS...185 MPH...295 KM/H PRESENT MOVEMENT...WNW OR 285 DEGREES AT 15 MPH...24 KM/H MINIMUM CENTRAL PRESSURE...916 MB...27.05 INCHES DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 PM AST (0300 UTC), the eye of Hurricane Irma was located near latitude 17.4 North, longitude 61.1 West. Irma is moving toward the west-northwest near 15 mph (24 km/h), and this motion is expected to continue for the next couple of days. On the forecast track, the extremely dangerous core of Irma will move over portions of the northern Leeward Islands tonight and early Wednesday, move near or over portions of the northern Virgin Islands Wednesday, and pass near or just north of Puerto Rico late Wednesday and Wednesday night. Maximum sustained winds remain near 185 mph (295 km/h) with higher gusts. Irma is a 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 50 miles (85 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The minimum central pressure estimated from Air Force and NOAA Hurricane Hunter aircraft observations is 916 mb (27.05 inches). Stephen Indianapolis IN |

Data from Barbuda as the western eye wall moved through reveal wind gusts in excess of 150 mph before dropping falling calm as the eye crossed, while MSLP fell close to 920 hPa.
