At 05:00 hr PDT the center of Hurricane Polo was located about 820 km - 510 mi SE of the southern tip of Baja California. Polo is moving toward the west-northwest near 13 km/h - 8 mph. A turn toward the northwest is expected later today with a northwestward motion continuing through Saturday.
On the forecast track Polo will move parallel to the southwestern coast of Mexico.
However any deviation to the north of the track could bring stronger winds to the coast.
The storm is close enough to the coast that a Tropical Storm Warning has been issued for the coast of southwest Mexico.
Maximum sustained winds remain near 120 km/h - 75 mph with higher gusts.
Some strengthening is possible today and tonight.
After that Polo is expected to weaken due to unfavourable upper-level winds. An Air Force reconnaissance plane is scheduled to investigate Polo later today.
Residents and stranded visitors in Baja California should continue to keep an eye on Hurricane Polo.
The outer bands of Hurricane Polo are currently bringing rain to parts of the southwestern Mexican coast.
Periods of strong winds, heavy rain, high surf and rip currents may eventually affect portions of the coast.
Rainfall amounts of 5-10 inches are expected with isolated totals of 15 inches possible near the coast of the Mexican states of Guerrero, Michoacan, Colima and Jalisco.
The heavy rain brings the threat of flash flooding and mudslides.
Hurricane Polo, the sixteenth named storm of a busy eastern Pacific hurricane season, formed Tuesday several hundred miles south-southeast of Acapulco, Mexico.
It became the season's eleventh hurricane on Wednesday.
