before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.
 
A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area within 36 hours.
 
Interests elsewhere along the west-central coast of Mexico and
southern portions of Baja California Sur should monitor the progress
of Nora.  Additional watches and warnings will likely be required
for portions of these areas tonight and on Friday.

For storm information specific to your area, please monitor
products issued by your national meteorological service.

located near latitude 13.4 North, longitude 101.7 West.  Nora is
moving toward the west-northwest near 9 mph (15 km/h).  A motion 
toward the northwest and north-northwest is expected to begin 
tonight and continue through Sunday.  On the forecast track, the 
center of Nora will approach the southwestern coast of Mexico 
Friday and Friday night and be very near the coast Saturday and 
Saturday night.  Nora will then approach the southern portion of 
Baja California Sur on Sunday.

Strengthening is forecast during the next few days, and Nora is 
expected to become a hurricane on Saturday.

Tropical storm conditions are expected within the tropical storm

RAINFALL:  Nora is expected to produce heavy rains over coastal
sections of the Mexican states of Oaxaca, Guerrero, Michoacan,
Colima, and Jalisco.  Rainfall totals of 8 to 12 inches are
forecast through this weekend with isolated maximum amounts of 20

Mexico and will spread northward to the southwestern coast of
Mexico through the end of the week.  These swells are likely to
cause life-threatening surf and rip current conditions.  Please
