Stunning picture - thanks for that. I haven't been able to find anything about its central pressure or whether or not it will deepen.

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).
