If the system turns into a tropical depression, the NHC will begin issuing official advisories, including coordinates, wind speeds, motion and a forecast track. It's been slowly moving to the northwest and is headed for the Gulf once it crosses Mexico's Yucatan Peninsula.
As of Monday evening, the storm was expected to become a tropical storm either overnight or during the day Tuesday, according to Roger Erickson, warning coordinator for the local National Weather Service office.
TROPICAL FIRST ALERT UPDATE: A little later today we could see two tropical disturbances form into tropical cyclones. Sustained winds have reached 40 miles per hour.
Tropical Storm Bret is expected to weaken as it moves across the Caribbean Tuesday while a second, larger system rolling across the Gulf of Mexico appears to be intensifying.
However, after the storm develops into a tropical storm, it is expected to encounter unfavorable conditions in the Caribbean, dissipating later in the week. It is important to note at this time that the models DO NOT have a great handle on the system yet as it does not have a well defined center of circulation.
Name or no name, the hurricane center said Invest 93L will dump a lot of rain on parts of Central America, the Yucatan Peninsula, Jamaica, the Cayman Islands and western Cuba over the next several days.
As an upper-level trough moves east, it is possible the moisture associated with any development would interact and be pulled slightly east as well.
The National Hurricane Center is also keeping an eye on Potential Tropical Cyclone Three in the central Gulf of Mexico. It is packing winds of 40 miles per hour.
