MARC HAS WEAKENED TO A TS @ 70MPH
EXPECTED TO APPROACH LOUISIANA BY MON AFTERNOON
~~~~~~~~~~~~~~~~~~~~~~~
At 1000 PM CDT (0300 UTC), the center of Tropical Storm Marco was
located by an Air Force Reserve Hurricane Hunter plane near latitude
26.8 North, longitude 87.6 West. Marco is moving toward the
north-northwest near 12 mph (19 km/h). A continued
north-northwestward motion is possible tonight, but a turn toward
the northwest is expected by Monday morning. Marco is forecast to
approach the coast of Louisiana by Monday afternoon, and then turn
westward and move near or over the coast through Tuesday.
Data from the Hurricane Hunter plane indicate that maximum sustained
winds have decreased to near 70 mph (110 km/h) with higher gusts.
Fluctuations in intensity are possible during the next 24 hours, but
Marco is forecast to weaken rapidly by early Tuesday.
Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.
The estimated minimum central pressure based on data from the
reconnaissance aircraft is 1000 mb (29.53 inches).
