DISCUSSION AND 48-HOUR OUTLOOK
At 200 PM PDT (2100 UTC), the center of Tropical Storm Lidia was
located near latitude 28.8 North, longitude 115.0 West. Lidia is
moving toward the northwest near 12 mph (19 km/h) and the system is
expected to turn toward the west-northwest at about the same rate
of forward speed during the next two days.
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Some weakening is forecast during the next 48 hours. Lidia is
expected to weaken to a tropical depression tonight and become a
remnant low on Sunday.
Tropical-storm-force winds extend outward up to 175 miles (280 km)
from the center. A Mexican Navy observation site at Isla Cedros
recently recorded a wind gust of 39 mph (63 km/h).
The estimated minimum central pressure is 999 mb (29.50 inches).
HAZARDS AFFECTING LAND
RAINFALL: Lidia is expected to produce total rain accumulations of
4 to 8 inches across the Mexican states of Baja California Sur into
Baja California and the coastal section of Sonora and northern
Sinaloa, with isolated maximum amounts of 12 inches. These rains may
cause life-threatening flash floods and mudslides. Some of the
tropical moisture from Lidia will spread across parts of the desert
Southwest through this holiday weekend for an increase in scattered
showers and thunderstorms, from southern Nevada and western Arizona
into southern California.
WIND: Tropical storm conditions are occurring over portions of the
warning area in the Mexican state of Baja California, along the
coast of the Gulf of California. These conditions should persist
for the next few hours. Wind speeds atop and on the windward sides
of hills and mountains are often up to 30 percent stronger than the
near-surface winds indicated in this advisory, and in some elevated
locations could be even greater.
STORM SURGE: Some coastal flooding is possible in areas of onshore
winds along the Baja California peninsula. Near the coast, the
surge will be accompanied by large waves.
SURF: Swells generated by Lidia are affecting portions of the coast
of western mainland Mexico and the west coast of Baja California
Sur. These swells could cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
Next intermediate advisory at 500 PM PDT.
