Tropical Storm Rafael is expected to weaken as the NHC tracks another system in the Caribbean that is expected to move into "unfavorable conditions."

Tropical Storm Rafael is expected to dissipate in the Gulf of Mexico before it reaches land but could generate life-threatening rip currents along the Gulf Coast through the weekend, forecasters with the National Hurricane Center in Miami said Sunday.

The biggest impacts from Rafael's storm bands may affect offshore oil and gas production. Several companies evacuated workers from rigs as Rafael remains near oil rigs in the Gulf of Mexico. Once Rafael takes a more southerly path, Northern Mexico may also begin experiencing higher wave heights and high surf along the beaches.
