Expected Impacts

Hurricane Irma will bring storm surges of  7 to 11 feet, possibly destructive winds, and rainfall exceeding a foot to the Leeward Island later today and Tuesday. The rainfall could produce flash flooding and mudslides in mountainous areas. Irma will approach and pass near the Virgin Islands and Puerto Rico later Tuesday and Wednesday. In those areas, it will bring the same severe hurricane conditions.

A strong Atlantic high pressure positioned to the north of Irma continues to guide the storm. Irma’s center will move very close, if not right over the northern Leeward Islands late Tuesday. It will then likely come very close to Puerto Rico, the Dominican Republic, and Cuba during the midweek.

Westward Track & Warm Water

Following the passage of an East Coast cold front, a high-pressure ridge settling in will help keep Irma on a westward track. This means the southern Bahamas and Cuba could be Irma’s next target Friday into early next weekend. Beyond that, it’s looking increasingly likely that Irma could turn more towards the north and impact Florida late in the weekend or early next week.

Warm water along Irma’s path will allow it to maintain its major Hurricane status. Some fluctuation in strength is possible. A hurricane this intense could lead to catastrophic damage along its path. Therefore, Irma will need to be closely monitored if you live in or have plans in the Caribbean Islands or along the Eastern U.S.

Hurricane Preparation

Preparation plans should be developed, including putting together a hurricane survival kit and planning evacuation routes from your area. Multiple routes should be considered in case your preferred one is blocked. If you own a business in a targetted area, it’s important that you take the proper precautions before the storm hits. This business checklist for hurricane preparedness should help you get ready.

This storm just comes two weeks after Hurricane Harvey. Irma is the fourth hurricane this season. It formed on the final day of August off of the west coast of Africa. Irma is also the second major hurricane of the season. In a normal season, the second major hurricane often doesn’t form until October 3rd.

    1. Thanks for sharing, Janice! Stay dry – We know it’s a dreary, rainy day in MD (and most of the East Coast) today.
