Hurricane Irma on September 5.

Hurricane Irma is a powerful Category 5 storm with 185 mph winds. However, what effect, if any, could the hurricane have on Boston, Massachusetts?

“Long-range forecasts indicated Irma likely would curve to the northwest beginning late Monday and skirt to the north of the islands in the eastern Caribbean on a path that could potentially take it to the U.S. East Coast, but it was too early to make a definitive prediction,” reported WCVB-TV. “StormTeam 5 said if the hurricane is going to make an East Coast impact, it would happen early next week, based on the current track of the storm.”

The initial danger is to Puerto Rico and the Virgin Islands, with the storm then likely proceeding to Southern Florida, including the Florida Keys, where evacuation orders were issued on September 5.

According to The Boston Globe, the storm’s danger to New England depends on its trajectory and, on September 5, that was too hard to predict.

“We know Irma is going to continue in a general westward movement the rest of the week. We also know eventually it’ll take a turn to the north. The precise timing of the turn is critical to how the United States is affected. If the turn occurs early enough, the storm could move along the coastline and not hit any land,” The Globe reported. “If the change in direction occurs just south of Florida, the storm could move through that state and then head north along the coast affecting multiple regions, even New England. The storm would weaken dramatically along the way but still create issues here sometime late next week.”

There are other models that don’t show the storm having much effect on New England.
