DISCUSSION AND OUTLOOK
----------------------
At 1200 PM MDT (1800 UTC), the center of Tropical Storm Lidia was
located near latitude 18.0 North, longitude 111.5 West. Lidia is
moving toward the east-northeast near 6 mph (9 km/h). A faster
east-northeastward motion is expected later today and Tuesday. On 
the forecast track, the center of Lidia should approach Las Islas 
Marias on Tuesday, and move inland over west-central Mexico Tuesday 
night.
 
Maximum sustained winds have increased to near 70 mph (110 km/h) 
with higher gusts.  Strengthening is forecast later today and 
Tuesday, and Lidia is expected to be a hurricane when it approaches 
Las Islas Marias and the coast of west-central Mexico.
 
Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center.
 
The minimum central pressure based on data from the Air Force 
Hurricane Hunters is 986 mb (29.12 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Lidia can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC
and on the web at hurricanes.gov/text/MIATCDEP5.shtml
 
RAINFALL:  Lidia is expected to produce rainfall totals of 4 to 8
inches with local maxima of 12 inches through Wednesday across the
state Nayarit, southern portions of the state of Sinaloa, and
coastal portions of the state of Jalisco in western Mexico. These
rains will likely produce flash and urban flooding, along with
possible mudslides in areas of higher terrain near the coast.
 
STORM SURGE:  A dangerous storm surge is expected to produce
significant coastal flooding near and to the south of where
the center makes landfall.  Near the coast, the surge will be
accompanied by large and dangerous waves.
 
WIND:  Hurricane conditions are expected to reach the warning area
on Tuesday, with winds expected to first reach tropical
storm strength by early Tuesday, making outside preparations
difficult or dangerous. Preparations to protect life and property
should be rushed to completion. Tropical storm conditions are
expected in the Tropical Storm Warning areas beginning Tuesday.
 
SURF: Swells generated by Lidia will affect the west coast of Mexico
and the Baja California peninsula for 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.
