Tropical Storm Calvin Forms: Flood and Mudslide Threat in Mexico and Central America
Published: June 12, 2017
Tropical Storm Calvin has formed and is moving very slowly near the Pacific coast of Mexico, where heavy rain could cause life-threatening flash floods and mudslides early this week.
Here's the latest from the National Hurricane Center:
Current Storm Status
Tropical Storm Calvin is expected to move slowly west-northwestward and push inland along the coast of southern Mexico by early Tuesday morning.
Little change in strength is expected until landfall, and weakening will occur after the storm's center moves inland.
Tropical storm warnings continue over parts of the southeastern Mexican coast from Boca de Pijijiapan to Punta Maldonado.
Tropical-storm-force winds – 39 mph or greater – have likely begun over portions of the warning area but should subside by early Tuesday morning.
Tropical Storm Watches/Warnings
Regardless of Calvin's strength, heavy rain is the main threat to Mexico and southern Guatemala.
Five to 10 inches of rainfall are forecast across the Mexican states of Chiapas, Oaxaca and Guerrero, with isolated amounts up to 20 inches possible. More than 6 inches have already fallen in Oaxaca and Salina Cruz in the Mexican state of Oaxaca.
Calvin is also expected to produce rainfall totals of 4 to 6 inches in the Mexican states of Tabasco and Veracruz, as well as in southern Guatemala. More than 5 inches have fallen in the city of Veracruz, as of late Monday afternoon.
These rainfall totals could lead to life-threatening flash floods and mudslides in some areas into midweek.
