Subtropical Storm Beryl to Dissipate as it Tracks Away From the U.S.

July 15, 2018

Beryl's remnants redeveloped as a subtropical storm in the northern Atlantic Ocean on Saturday, almost a week after the former hurricane dissipated while approaching the Caribbean.

Subtropical Storm Beryl is located over 400 miles south of Halifax, Nova Scotia.


Current Storm Status

This system became better organized Saturday morning, and the National Hurricane Center reinitiated advisories on Beryl.

Beryl is not a threat to the U.S., but some rain associated with it could impact Newfoundland, which was just brushed by former Hurricane Chris late last week. Beryl will not have tropical characteristics as it tracks near Atlantic Canada.

Beryl's Caribbean Impacts

The remnants of Beryl brought gusty winds, rough surf and dangerous rip currents to the Virgin Islands and Puerto Rico on July 9.

Heavy rain then spread into the Dominican Republic July 9 into July 10 when flooding was reported in the capital, Santo Domingo, where more than 9 inches fell in 24 hours.

Hundreds of homes were flooded, and more than 100,000 lost power in the Dominican Republic, according to the Miami Herald.

Beryl's History

Given barely enough ocean-heat content (sea-surface temperatures around 80 degrees), low wind shear and its location south of a plume of sinking, dry air known as the Saharan air layer, Beryl intensified quickly from a tropical depression at 11 a.m. EDT July 5 to a Category 1 hurricane just 18 hours later.

Wind shear combined with dry air caused Beryl to fall apart by July 8, and the National Hurricane Center issued its final advisory on the storm late on July 8.

The formation and intensification of a system in the central tropical Atlantic, known as the Main Development Region (MDR), in early July is fairly rare. 

In fact, it's only one of two such hurricanes to form this early in the season east of the Lesser Antilles. 

Tropical waves, the origin of many late-summer and early-fall hurricanes and the predecessor disturbance for Beryl, typically don't have enough moisture in July to become better developed.

In addition, Beryl's track was at a fairly low latitude.

The name "Beryl" has been used six times since 1982, each time as a tropical storm. This iteration of Beryl is the first one to become a hurricane.

Historical tracks and intensities of former Beryls.

The average second tropical storm forms Aug. 1 while the average first hurricane doesn't occur until Aug. 10. Beryl formed on July 5 and became a hurricane a day later.
