Tropical Storm Boris has formed and is poised to bring significant rainfall, potential flooding, and dangerous mudslides to parts of southern Mexico's Pacific coast, according to the U.S. National Hurricane Center.
The storm was last located approximately 85 miles southeast of Acapulco and 50 miles southwest of Punta Maldonado.
Boris is currently moving northeast at 2 mph with maximum sustained winds of 40 mph.
Forecasters anticipate that Boris will turn northward, delivering 4 to 10 inches of rain to coastal areas of Guerrero and Oaxaca states through Monday night.
Landfall is expected along the Guerrero coast by Monday evening. The National Hurricane Center warned, "This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain."
A tropical storm warning is in effect for the region stretching from Laguna de Chacahua in Oaxaca to Tecpan de Galeana in Guerrero, with tropical storm conditions expected within 24 hours.
Boris marks the second named storm of the Pacific hurricane season, which commenced on May 15. The first, Tropical Storm Amanda, formed on June 3 far out at sea and posed no threat to land.
The Atlantic hurricane season began on June 1, but has yet to see any cyclones this year.
