DISCUSSION AND OUTLOOK

At 800 PM PDT (0300 UTC), the center of Tropical Storm Iselle was
located near latitude 17.6 North, longitude 115.5 West. Iselle is
moving toward the north-northeast near 3 mph (6 km/h), and this
general motion is expected to continue through Friday night. A
northward and then northwestward motion is expected during the
weekend.
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Some strengthening is possible overnight, but Iselle is expected to
begin to gradually weaken late Friday.
Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.
The estimated minimum central pressure is 999 mb (29.50 inches).
HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Iselle and a large area of southwesterly
winds to its south are affecting portions of the southwestern coast
of Mexico and are expected to spread northward along the coast of
west-central Mexico and the southern Baja California peninsula
tonight and continue through Sunday. These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
