Post-Tropical Cyclone 01 (Arlene) is dissipating in the north Atlantic…remaining away from land areas

Tropical Storm 01L was the first April system since 2003. Since 1851…only seven tropical systems have formed before May 9th.

This makes the third straight year that a system has formed in the Atlantic…before the official June 1st start of the hurricane season.

TC Ana back in 2003 was the last April named storm in the Atlantic Basin. Ana began as a sub-tropical storm on April 20, 2003, and soon gained full tropical characteristics. That made Ana the only tropical storm on record to form in the Atlantic Basin in April.

The Atlantic hurricane season does not officially begin until June 1st and extends through November 30th.

Despite this earlier than usual activity, many forecasters expect this year to be slightly quieter than usual.

According to the National Hurricane Center (NHC), Arlene has become embedded within the circulation of a large extratropical cyclone, and lost most of its deep convection…while surrounded by cold air.

The post-tropical cyclone will move toward the southwest and south at about 20 knots…until dissipation occurs later today.

This is the last advisory on Arlene.
