The storm is projected to make its closet approach to the coast tonight or early Tuesday. The most significant impact is likely to be torrential rains, flash flooding and the resultant mudslides. Up to 6-12 inches of rain is projected by the National Hurricane Center along the coasts of the states of Guerrero, Jalisco, Colima, and Michoacan with isolated amounts to 20 inches in the mountainous terrain.

In addition to the rain, storm surge flooding along with “large and destructive” waves are possible within the hurricane warning area.

Although the storm’s strongest winds of potentially hurricane force are likely to remain offshore, the probability of at least tropical storm force winds of 39 mph or higher ranges from 50-90 percent in the warned area.

The current intensity forecast strengthens Beatriz’ maximum sustained winds to 90 mph by 2 p.m tomorrow. The storm currently sits over favorable very warm water of around 85 degrees. In addition, wind shear - which is hostile to storms - is light. However, gradual weakening is forecast to commence Wednesday once the storm moves over cooler water in the open Pacific.
