The storm is forecast to gradually strengthen, becoming a hurricane on Sunday before making landfall over the southern coast of Mexico on Monday. Mexico has issued a hurricane watch for the southern coast from Salina Cruz to Punta Maldonado.
“Storm surge could produce coastal flooding near and to the east of where the center passes the coast in areas of onshore winds,” the National Hurricane Center said. “The surge may be accompanied by large and destructive waves.”
In addition to storm surge, heavy rains from Agatha will hit portions of southern Mexico by Sunday into Tuesday night.
“The heaviest rain is forecast across the Mexican state of Oaxaca, where 10 to 16 inches are expected but isolated totals up to 20 inches is possible,” the hurricane center said.
