DISCUSSION AND OUTLOOK
At 700 AM CDT (1200 UTC), the center of Tropical Storm Karl was
located near latitude 22.1 North, longitude 94.1 West. Karl is
moving toward the southeast near 2 mph (4 km/h). A slightly
faster southeastward motion is expected later today. Karl is then
expected to turn southward or south-southwestward over the Bay
of Campeche on Friday. On the forecast track, the center of Karl
should reach the coasts of Tabasco or Veracruz states in Mexico
late Friday night or early Saturday.
Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. Little change in strength is expected today, but Karl should
gradually lose some strength on Friday while it approaches the Bay
of Campeche coast of Mexico.
Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center.
The minimum central pressure estimated from Air Force Reserve
reconnaissance aircraft and buoy data is 1002 mb (29.59 inches).
NOAA buoy 42055 located just east of Karl recently reported a
minimum pressure of 1004 mb (29.64 inches).
