The 2021 tropical storm and hurricane season – which doesn't officially begin until June 1 – appears to be jumping the gun yet again.

The National Hurricane Center is monitoring two separate areas for possible tropical development, one in the Gulf of Mexico and the other in the Atlantic east of Bermuda.

In the Gulf, forecasters said a short-lived tropical depression or storm could form before the system moves inland Friday night. Regardless of development, the system could produce heavy rainfall over portions of already sodden southeast Texas and southwestern Louisiana through the weekend, the hurricane center said.

Several additional inches of rain could fall in areas that have already picked up nearly 20 inches of rain near the coastline of southeast Texas and southwest Louisiana, AccuWeather said.

Even after the disturbance in the Gulf moves inland Friday night, downpours can persist into Saturday and are likely to focus on the areas that have already been doused over and over again this week, AccuWeather forecasters said.

Meanwhile, in the Atlantic, a separate system located about 450 miles east-northeast of Bermuda has a 90% chance of development over the next two days. Forecasters believe it could form into a subtropical depression or storm Friday as it moves west to southwest to the northeast of Bermuda. 

A direct impact on the U.S. is not expected with this system, according to AccuWeather, as it's not expected to last more than a couple of days once it forms.

The first two names on the storm list are Ana and Bill. Whichever storm strengthens enough to become a named system first will be given the name Ana.

On Thursday, federal forecasters from the National Oceanic and Atmospheric Administration said the 2021 hurricane season should be a busy one, with up to 20 named storms possible. It's not expected to approach the hyperactive season of last year, however, when 30 named storms formed, including 14 hurricanes.

There’s a 60% chance that this hurricane season will be busier than normal and only a 10% chance it will be below normal, NOAA said.

About half the years in the last decade have had named storms before the June 1 start of hurricane season.
