Forecasters Warn Tropical Storm Laura Will Become Hurricane VOA News Tropical Storm Laura is likely to become a hurricane Tuesday as it heads into the warm waters of the Caribbean, forecasters warn, while its twin storm Marco is losing strength but will still produce heavy and high winds as it approaches the Gulf Coast of the southern United States. The [1]National Hurricane Centersays that, as of midday Monday, Marco was within 90 kilometers of the mouth of the Mississippi River on the Louisiana coast. A strong, steady southwesterly wind shear weakened Marco, which, some models predicted, could become a hurricane. References 1. https://www.nhc.noaa.gov/ .
