Published: June 12,2017

Tropical Storm Calvin is making landfall along the Pacific coast of southeastern Mexico, where heavy rain could cause life-threatening flash floods and mudslides early this week.
Here's the latest from the National Hurricane Center:
  • Tropical Storm Calvin is located about 50 miles east-northeast of Puerto Angel, Mexico.
  • The center of Calvin will be moving inland along the coast of southeastern Mexico overnight into early Tuesday morning.
  • Life-threatening flash floods and mudslides are possible in southeastern Mexico and southern Guatemala.
  • This system is no threat to the U.S. mainland.

Current Storm Status
Tropical Storm Calvin is expected to move slowly west-northwestward and push inland along the coast of southeastern Mexico overnight into early Tuesday morning.
Weakening will occur now that the center is moving inland.

Projected Path
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 – 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 had already fallen in Oaxaca and Salina Cruz in the Mexican state of Oaxaca as of late Monday afternoon.
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 had 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.
