DISCUSSION AND OUTLOOK
----------------------
At 1100 AM MST (1800 UTC), the eye of Hurricane Polo was located by 
NOAA Hurricane Hunter aircraft near latitude 24.5 North, longitude 
113.5 West. Polo is moving toward the northeast near 10 mph      
(17 km/h) and this motion with gradual acceleration is expected this 
afternoon through Tuesday. On the forecast track, the center of Polo 
is expected to make landfall along the west coast of Baja California 
Sur this evening, then move inland into southern Sonora on Tuesday 
morning.
 
Maximum sustained winds are near 115 mph (185 km/h) with higher 
gusts. Polo is a category 3 hurricane on the Saffir-Simpson 
Hurricane Wind Scale. Fluctuations in intensity are possible today. 
However, Polo is forecast to be near major hurricane strength when 
it reaches Baja California Sur this evening, and is expected to be a 
hurricane when it makes landfall in mainland Mexico early Tuesday 
morning. Rapid weakening is expected after Polo moves farther 
inland into mainland Mexico. 
 
Hurricane-force winds extend outward up to 40 miles (65 km) from the 
center and tropical-storm-force winds extend outward up to 105 miles 
(165 km). Recently, a wind gust of 46 mph (74 km/h) was observed in 
Puerto Cortes, Mexico. 
 
The minimum central pressure measured by aircraft dropsonde data is 
964 mb (28.47 inches). 
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Polo can be found in the Tropical Cyclone
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 late this afternoon, 
with tropical storm conditions already occuring in the southern 
portion of the warning area. These conditions are expected to spread 
northward and eastward across Baja California Sur this afternoon 
and tonight. Hurricane conditions are expected within the Hurricane 
Warning area and are possible in the watch area in mainland 
northwestern Mexico early Tuesday with tropical storm conditions 
expected to begin tonight.
 
RAINFALL: Polo is expected to produce rainfall totals of 6 to 12
inches across portions of Baja California Sur. Rainfall totals of 4
to 6 inches with maximum totals of 8 inches are expected across
southern and central portions of Sonora. This rainfall may produce
life-threatening flooding and mudslides, especially in areas of
steep terrain.
 
For a complete depiction of forecast rainfall associated with Polo,
please see the National Weather Service Storm Total Rainfall Graphic
available at hurricanes.gov/graphics_ep2.shtml?rainqpf
 
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
west-central Mexico and the Baja California peninsula during the
next couple of days. These swells are likely to cause
life-threatening surf, rip currents, and coastal flooding. Please
consult products from your local weather office.
