Tropical Storm Boris and Tropical Depression Three-E form in the Eastern Pacific, threatening flooding rain

Tropical Storm Boris formed early Monday about 85 miles southeast of Acapulco, Meixico, and could bring up to a foot of rain to the popular tourist destination.

MEXICO - Tropical Storm Boris is churning about 80 miles southeast of Acapulco, Mexico, and could bring up to a foot of rain to the popular tourist destination. Meanwhile, Tropical Depression Three-E formed about 90 miles west-southwest of Managua, Nicaragua, late Monday morning as tropical activity increases in the Eastern Pacific.

WHAT IS A TROPICAL DEPRESSION?

 Tropical Storm Boris formed in the Eastern Pacific early Monday and has maximum sustained wind speeds of 40 mph and is moving north at 3 mph.

WHAT’S THE DIFFERENCE BETWEEN A TROPICAL DEPRESSION, TROPICAL STORM AND HURRICANE?

A Tropical Storm Warning is in effect from Laguna de Chacahua to Tecpan de Galeana. The National Hurricane Center (NHC) said Boris could produce life-threatening flash flooding as it quickly moves ashore as early as Monday afternoon.

Boris quickly developed from Tropical Depression Two-E early Monday.

Farther to the south and closer to Central America, Tropical Depression Three-E developed from Invest 92E later Monday morning, with sustained winds of 35 mph.

The NHC said Three-E could bring heavy rain and life-threatening flash flooding to Costa Rica, Nicaragua, Honduras, El Salvador and Guatemala through mid-week. Both Nicaragua and El Salvador have issued Tropical Storm Warnings.

WHAT IS AN INVEST DURING HURRICANE SEASON?

The term "invest" is used every hurricane season in the Atlantic and the Eastern and Central Pacific basins, accompanied by a number from 90 to 99 and either the suffix "L," "E" or "C," respectively.

Meanwhile, Amanda, the first tropical storm of the season, which had been downgraded to a tropical depression earlier Sunday, further weakened and became post-tropical late Sunday over the open ocean.

Sea surface temperatures near Mexico and farther west into the open Pacific Ocean are currently running well above their seasonal average and are expected to further warm in the coming weeks, becoming even more favorable for development.

Tropical development at this point in the year is right on schedule, as the first named storm in the East Pacific typically forms around June 10.
