Public Information Statement
NWS National Hurricane Center Miami FL
800 AM EST Tue Mar 2 2021

To: NWS Partners, Users, and Employees

From: Michael J. Brennan
Branch Chief, Hurricane Specialist Unit
National Hurricane Center

Subject: Routine issuance of the Atlantic basin
Tropical Weather Outlook beginning on May 15, 2021

In order to provide more frequent information on the potential for
tropical cyclone formation as the official June 1 start of the
Atlantic hurricane season approaches, the National Hurricane Center
will begin routine issuance of the Atlantic Tropical Weather Outlook
(TWO) and the Graphical TWO at 800 AM EDT (1200 UTC) May 15, 2021.

Given recent increased tropical cyclone activity in the Atlantic
basin in late May, routine issuance of the Atlantic TWO starting on
May 15 offers a service improvement over unscheduled Special TWOs
that are issued to discuss the possibility of tropical cyclone
formation prior to the official start of hurricane season on
June 1.

The Atlantic TWO can be found under AWIPS header MIATWOAT and WMO
header ABNT20 KNHC. The TWO and Graphical TWO can also be found
online at hurricanes.gov.


An effect of global warming, perhaps.
