Riviera Maya, Q.R. — The first monitored weather disturbance of the 2021 Atlantic Hurricane season has been located in the basin. On Wednesday, the National Oceanic and Atmospheric Administration (NOAA) reported the disturbance as having a 40 percent chance of further development over a 5-day period.
On Thursday, the NOAA updated its forecast, which it now says has a 90 percent chance of further development over the next five days. The disturbance, Invest 90L which is a non-tropical low pressure system, is located 800 miles east of Bermuda and does not pose any risk to Mexico.
However, it is expected to further develop into a subtropical cyclone by Friday as it continues to move toward Bermuda then backtrack out to sea. The agency says it will continue to monitor the system’s development. In the event Invest 90L does develop, it would be the seventh year in a row the Atlantic has recorded an early start to the hurricane season.
Earlier this year, the NOAA announced they would begin storm monitoring May 15, an increase of two weeks from their usual June 1 start date due to the early development of storms over the past several seasons.
Last week, a system in the Eastern Pacific developed early, already providing the region with Andres, their first named storm of the year.
UPDATE: As of early Saturday morning, subtropical storm Ana formed in the Atlantic, according to the National Hurricane Center. Ana was located about 200 miles northeast of Bermuda with maximum sustained winds of 45 mph. While there was a storm watch in effect for Bermuda, that has since been dropped since Ana is expected to head out to sea and dissipate by Monday.
