DISCUSSION AND OUTLOOK
At 100 PM CDT (1800 UTC), the center of Tropical Storm Barry was
located by NOAA Doppler radars and surface observations near
latitude 32.4 North, longitude 93.6 West. Barry is moving toward the
north-northwest near 9 mph (15 km/h). A general northward motion
is forecast tonight 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 northwestern portions of Louisiana today, and over Arkansas
tonight and Monday.
NOAA Doppler weather radar data and surface observations indicate
that maximum sustained winds remain near 40 mph (65 km/h) with
higher gusts. These winds are occurring near the coast well to
the southeast and south 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 185 miles (295 km)
to the southeast of the center. A sustained wind of 41 mph (67 km/h)
and a gust to 48 mph (78 km/h) was recently reported at an NOS site
at Calcasieu Pass, Louisiana.
The estimated minimum central pressure is 1007 mb (29.74 inches).
