At 11 a.m. Saturday, the National Hurricane Center issued an advisory stating that Tropical Storm Jerry is in the Atlantic Ocean, 435 miles north of the Northern Leeward Islands and 545 miles south of Bermuda. It is moving to the north at 16 mph, with maximum sustained winds of 60 mph.

The National Hurricane Center was tracking two storms on Friday, but neither was a threat to the United States. However, those along the East Coast are expecting to deal with a non-tropical coastal storm over the weekend that will bring some tropical-storm-like effects to areas from the Carolinas to possibly New England.

Most Atlantic tropical systems form much farther south—in the tropical Atlantic, Gulf of Mexico or Caribbean—where warm sea surface temperatures and humid air foster cyclogenesis. The current system, however, is forming in cooler northern waters and under increasing wind shear, making tropical development rare but not impossible.

According to the National Hurricane Center's 2 a.m. Thursday advisory, Tropical Storm Jerry is in the Atlantic Ocean, 440 miles east-southeast of the Northern Leeward Islands. The system, with maximum sustained winds of 65 mph, is moving to the west-northwest at 18 mph.
