Tropical Storm Irma Forms in the Atlantic Ocean

30 Aug 2017, 2:32 pm

Tropical Storm Irma developed earlier today in the Atlantic Ocean. Irma is the 9th named storm of the 2017 Atlantic tropical season. According to the National Hurricane Center, satellite images indicate that Irma has become much better organized since yesterday, with many curved rain bands around the center.  The cyclone is well out into the Eastern Atlantic Ocean, 420 miles west of the Cape Verde Islands. The storm is no threat to any land areas in the near future, as it moves west at 13 mph. Maximum sustained winds are at 50 mph.

A ridge over the Eastern Atlantic Ocean is forecast to steer Irma westward over the next few days. Thereafter, the ridge builds southwestward, which will likely cause the storm to move, somewhat unusually, toward the west-southwest into the weekend and early next week.

Forecast models indicate that the upper-level winds are likely to be favorable for strengthening of Irma during the next several days. However, Irma will be moving over more marginal water temperatures and into drier mid-level conditions, which should temper the intensification rate. By the end of the week and into this weekend, conditions around the cyclone are expected to be more conducive for intensification. The National Hurricane Center forecasts the storm to become a hurricane Friday night.
