with higher gusts. Polo is a category 3 hurricane on the
Saffir-Simpson Hurricane Wind Scale. Fluctuations in strength are
possible over the next day or two, but Polo is forecast to remain a
strong hurricane when it reaches Baja California Sur on Monday.
 
Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 105 miles
(165 km).

Discussion under AWIPS header MIATCDEP2 and WMO header WTPZ42 KNHC.
 
WIND: Hurricane conditions are expected within the warning area
along the west coast of Baja California Sur by Monday afternoon,
with tropical storm conditions possible in the southern portion of
the warning area by tonight into early Monday. These conditions
are expected to spread northward during the day on Monday and then
eastward across Baja California Sur by Monday evening. Hurricane
conditions are possible within the Hurricane Watch area in mainland
northwestern Mexico on Tuesday.
 
RAINFALL: Polo is expected to produce rainfall totals of 4 to 8
inches with maximum amounts of 12 inches across portions of Baja
California Sur. Rainfall totals of 4 to 6 inches with maximum totals
of 8 expected across portions of Sonora.  This rainfall may produce
life-threatening flooding and mudslides, especially in areas of

SURGE: A storm surge could produce significant coastal flooding in
areas of onshore winds. Near the coast, the surge will be
accompanied by large and destructive waves.
 
SURF: Swells generated by Polo will continue affecting the coast of
southwestern Mexico, west-central Mexico, and Baja California Sur
during the next couple of days. These swells will spread northward
along the coast of the Baja California Peninsula through the
remainder of the weekend. These swells are likely to cause
life-threatening surf, rip currents, and coastal flooding. Please
consult products from your local weather office.
