DISCUSSION AND OUTLOOK
At 700 AM CDT (1200 UTC), the center of Tropical Storm Barry was
located near latitude 31.4 North, longitude 93.4 West. Barry is
moving toward the north near 6 mph (10 km/h), and this general
motion is expected to continue through Monday. On the forecast
track, the center of Barry will move across the western and northern
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 45 mph (75 km/h) with
higher gusts. These winds are occurring near the coast 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)
mainly over water to the southeast of the center. A sustained wind
of 39 mph (63 km/h) was recently reported at Cypremort Point,
Louisiana, located in Vermilion Bay.
The estimated minimum central pressure based on surface
observations is 1005 mb (29.68 inches).
