DISCUSSION AND OUTLOOK
----------------------
At 600 PM CST (0000 UTC), the center of Tropical Storm Mario was
located near latitude 17.8 North, longitude 103.8 West. Mario is
moving toward the west-northwest near 16 mph (26 km/h), and this
motion is expected to continue for the next several hours. A slower
motion toward the west-northwest is forecast later tonight through
the weekend. On the forecast track, the center of Mario should move
roughly parallel to the coast of Mexico through tonight, and then
begin to move farther away from the coast on Saturday.

Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts. Some strengthening is forecast during the next couple of
days.

Mario is a tiny tropical storm, and tropical-storm-force winds
extend outward up to 25 miles (35 km) to the north of the center.

The estimated minimum central pressure is 1006 mb (29.71 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL: RAINFALL: Tropical Storm Mario will lead to additional
rainfall of 1 to 3 inches, with locally higher amounts, for
especially Jalisco through Saturday morning. This brings a risk of
