DISCUSSION AND OUTLOOK
----------------------
At 1100 PM EDT (0300 UTC), the center of Post-Tropical Cyclone
Chantal was located near latitude 39.6 North, longitude 73.6 West.
The post-tropical cyclone is moving toward the northeast near 25 mph
(41 km/h) and this motion is expected to continue with an increase
in forward speed Monday night into Tuesday.
Maximum sustained winds are near 25 mph (35 km/h) with higher gusts.
Due to its forward motion and modest wind field, the cyclone's wind
field is becoming less defined. Post-Tropical Cyclone Chantal

The estimated minimum central pressure is 1011 mb (29.86 inches).
