Hurricane Center continues to watch 3 systems in Atlantic; strong winds expected on U.S. coasts

Atlantic hurricane season

The National Hurricane Center continues to keep an eye on three tropical systems in the Atlantic.

One system is expected to bring strong winds, coastal flooding and rough surf to portions of the mid- Atlantic and northeastern United States coasts through late week. A non-tropical low pressure system located about 1,000 miles east of Bermuda is producing winds to near gale force.

This system could still become a tropical or subtropical storm while it moves slowly west through today.

However, upper-level winds are expected to become unfavorable for further development by tonight.

Formation chance through 48 hours...medium...40 percent. Formation chance through 5 days...medium...40 percent.

System meandering off U.S. East Coast

Cloudiness and showers located off the mid-Atlantic coast of the United States are associated with a non-tropical area of low pressure that is producing gale-force winds.

This system is forecast to strengthen as a non-tropical low off the east coast of the United States during the next day or so.

Environmental conditions are now forecast to be less conducive for significant subtropical or tropical cyclone development through the end of the week as it meanders offshore the United States.

Regardless of development, this system is expected to bring strong winds, coastal flooding and rough surf to portions of the mid- Atlantic and northeastern United States coasts through late week.

Formation chance through 48 hours...low...10 percent. Formation chance through 5 days...low...20 percent.

System expected to merger with low off East Coast

A small area of low pressure located about 250 miles southeast of Cape Hatteras, North Carolina is producing showers and thunderstorms well east of the center.

Upper-level winds are only marginally favorable for some additional development today.

By tonight, the system is forecast to merge with the low off the East Coast of the United States.

Formation chance through 48 hours...low...20 percent. Formation chance through 5 days...low...20 percent.

An intense and long-duration storm will lash the mid-Atlantic and southern New England coasts with drenching rain, gusty winds, rough seas and flooding problems — and AccuWeather meteorologists said it could be the heaviest rain event in a few years in parts of the region.

Multiple storms will consolidate into one storm, which will strengthen and stall just offshore of the Atlantic coast through late in the week.

The stalled storm will focus Atlantic moisture along the mid-Atlantic and southern New England coasts, which will cause rain to drench some communities with several inches of rain.

"In southeastern New England, more general flash flooding can occur with 3-5 inches of rain forecast and an AccuWeather Local StormMax of 8 inches," said Tiffany Fortier, AccuWeather meteorologist.

This may be the most substantial, multiple-day rain event in a few years for part of southeastern New England.
