warning area. Tropical storm conditions are expected to continue
across portions of the warning area and in inland areas near the
center through early Saturday.
RAINFALL: Patricia is expected to produce total rainfall
accumulations of 8 to 12 inches, with isolated maximum amounts of
20 inches, over the Mexican states of Nayarit, Jalisco, Colima,
Michoacan, and Guerrero through Saturday. These rains are likely
to produce life-threatening flash floods and mudslides.
STORM SURGE: Water levels are expected to gradually subside
overnight but remain above normal through late Saturday. Near the
coast, large and destructive waves are forecast to continue
SURF: Swells generated by Patricia are likely to affect the
southwest coast of Mexico for the next day or so. These swells are
