(RNN) - Forecasters with the National Hurricane Center are watching two tropical systems in the Atlantic basin that have a potential to become tropical storms in the next couple of days.
The National Hurricane Center has issued advisories for what it calls Potential Tropical Cyclone Two, about 485 miles east-southeast of Trinidad, moving to the west at 23 mph. It is packing winds of 40 mph.
Because this storm is expected to develop into a tropical storm within the next 24 hours, a tropical storm warning has been issued for the Barbados, St. Vincent and the Grenadines, Trinidad, Tobago and Grenada.
However, after the storm develops into a tropical storm, it is expected to encounter unfavorable conditions in the Caribbean, dissipating later in the week.
A second system near the Yucatan also may become a tropical storm in the next 48 hours, even though the low lacks a well-defined center of circulation.
Forecasters said the system will move out into the central or southern Gulf on Monday and may be investigated by the Air Force Reserve Hurricane Hunter aircraft later Monday if needed.
It has a 80-percent chance of becoming a tropical system in the next 48 hours and a 90-percent chance of development in the next five days.
The next storm names on the 2017 list are Bret and Cindy, since Tropical Storm Arlene formed in the Atlantic in April.
Forecasters at the National Oceanic and Atmospheric Administration’s Climate Prediction Center said the Atlantic may have an above-average hurricane season this year, with a 70-percent likelihood of 11 to 17 named storms, of which five to nine could become hurricanes, including two to four major hurricanes.
