"Two strengthening tropical storms will bring serious wind and water threats to two coastal areas on Monday and Tuesday."
"Two named storms in less than 48 hours will slam into Mexico’s Pacific coastline early this week – one of them likely to be a strengthening hurricane – making for an unusual double-barreled threat. Yet another tropical cyclone will make landfall in the Pacific during the same period – this one expected to strike the U.S. Northern Mariana Islands as an intensifying typhoon.
First to make landfall will be Tropical Storm Max, which developed late Sunday off the coast of Guerro state west of Acapulco. As of 11 a.m. EDT Monday, Max was packing top sustained winds of 60 mph and was located about 50 miles south-southeast of Zihuatanejo, Mexico, moving north-northeast at 5 mph, with a central pressure of 996 millibars. On its current trajectory, Max will make landfall Monday afternoon or evening just east of Zihuatanejo as a strong tropical storm, possibly becoming a Category 1 hurricane just before landfall. Max’s compact area of strong winds will affect a sparsely populated section of coastal Mexico. However, the storm’s envelope of moisture will push upslope against the rugged terrain of Guerro state, especially just inland from roughly Acapulco to Làzaro Cardenas. Totals of four to eight inches of rain – and locally more than a foot – will raise a serious threat of flash flooding and mudslides.
Farther to the northwest, the much larger Tropical Storm Lidia is expected to vault to hurricane strength as it accelerates toward the coastlines of Jalisco, Nayarit, and Sinaloa states. Lidia is expected to make landfall late Tuesday near or just north of Puerto Vallarta, which could put that heavily populated area on the more dangerous right-hand side of the storm and push storm surge into the Bay of Banderas, where the city lies."
