Islands caught in the northwestern part of Irma’s eyewall will experience the strongest winds, and a storm surge—sea water pushed inland by a hurricane’s strong winds—deep enough to completely inundate buildings on the coast. The U.S. territories of Puerto Rico and the U.S. Virgin Islands will experience severe impacts from this storm on Wednesday. The National Hurricane Center expects the two island territories to see violent winds and up to a foot of rain as the eye of the storm moves just to their north. Wind damage is likely to hit trees, power lines, and buildings, especially those with lower construction quality. Storm surge flooding of 7 to 11 feet above normal tide levels is possible in the U.S. Virgin Islands (except for St. Croix), and a storm surge of 3 to 5 feet could occur on Puerto Rico’s northern coast. A storm surge is the sea water pushed inland by a hurricane’s strong winds. Islands caught in the northwestern part of Irma’s eyewall will experience the strongest winds and a storm surge that might be deep enough to completely inundate some buildings on the coast.
