Gradual weakening is forecast during the next 48 hours, and John is expected to become a tropical storm by late Thursday.

The estimated minimum central pressure is 972 mb (28.71 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: John is expected to produce total rain accumulations of 1 to 2 inches over far southern Baja California Sur, with isolated maximum amounts of 3 inches through Thursday. SURF: Swells generated by John will affect portions of the coasts of southwestern Mexico and the southern portion of the Baja California peninsula during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
