DISCUSSION AND OUTLOOK
At 1000 AM CDT (1500 UTC), the center of Tropical Storm Barry was
located by NOAA Doppler radars and surface observations near
latitude 31.8 North, longitude 93.4 West. Barry is moving toward the
north near 9 mph (15 km/h) and this general motion is forecast to
continue through Monday morning. A motion toward the north-northeast
and northeast is expected Monday afternoon into Tuesday. On the
forecast track, the center of Barry will move across the western and
northern portions of Louisiana today, and over Arkansas tonight and
NOAA Doppler weather radar data and surface observations indicate
that maximum sustained winds have decreased to near 40 mph (65 km/h)
with higher gusts. These winds are occurring near the coast well to
the southeast of the center. Weakening is expected as the center
moves farther inland, and Barry is forecast to weaken to a tropical
depression later today.
Tropical-storm-force winds extend outward up to 175 miles (280 km)
to the southeast of the center. A sustained wind of 39 mph (64 km/h)
and a gust to 49 mph (80 km/h) was recently reported at an NOS site
at Calcasieu Pass, Louisiana. A wind gust to 49 mph (80 km/h) was
also recently reported at a Weatherflow site at Cameron, Louisiana.
The estimated minimum central pressure is 1006 mb (29.71 inches).
