The National Hurricane Center on Thursday increased odds that a developing system could head into the Gulf of Mexico and become a tropical depression or storm — while it also kept tabs on two systems in the Atlantic.

The odds of a tropical disturbance developing in the northwestern Caribbean Sea and southeastern Gulf of Mexico have increased, according to the National Hurricane Center’s (NHC) Thursday advisory.

As tropical activity in the Atlantic Ocean quiets down again, attention is shifting back to the Caribbean and Gulf of Mexico, where the National Hurricane Center is now officially monitoring the area for tropical development.
