National Hurricane Center: Sub-Tropical Cyclone May Form In 24 Hours

MIAMI, Florida - An early-season subtropical cyclone may form off the United States within the next 24 hours, according to NOAA's National Hurricane Center in Miami, Florida.

A Tropical Weather Outlook issued by the NHC at 1:30 p.m. Eastern Standard Time on Tuesday, April 18, 2017, advised that a non-tropical low pressure system, dubbed Invest 91L, is located over the central Atlantic Ocean about midway between Bermuda and the Azores Islands.

This low is currently producing an area of gusty winds to the west of the center, with disorganized cloudiness and showers.  The system has a 30% chance of becoming a tropical cyclone during the next 24 hours.

NHC forecasters believe that environmental conditions could favor additional development and that Invest 91L has some potential to become a subtropical cyclone over the next day before it becomes absorbed by a larger ex-tropical cyclone.

Spaghetti models for Invest 91L are not in agreement on a projected path other than the system is likely to meander over the Atlantic Ocean during the next couple of days.

Forecasters are predicting a slightly below-average hurricane season this year.

The 2017 Atlantic Hurricane Season begins on June 1 and ends on November 30.
