WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.

Interests along the coast of North Carolina should monitor the
progress of this system.


DISCUSSION AND OUTLOOK
----------------------
At 500 AM EDT (0900 UTC), the center of Tropical Storm Chris was
located by an Air Force Reserve hurricane hunter aircraft near
latitude 33.0 North, longitude 75.5 West. Chris is forecast to
meander off the coast of the Carolinas for the next several days.
An acceleration toward the northeast is expected to begin on
Tuesday.

Data from an Air Force Reserve reconnaissance aircraft indicate that
the maximum sustained winds have increased to near 40 mph (65 km/h)
with higher gusts.  Additional strengthening is forecast, and Chris
is expected to become a hurricane by mid-week.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.

The estimated minimum central pressure from reconnaissance data is
1010 mb (29.83 inches).


HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Chris are expected to increase and affect
portions of the coasts of North Carolina and the mid-Atlantic states
into early next week.  These swells could cause life-threatening
surf and rip current conditions.  Please consult products from your
local weather office.

WIND:  Winds to gale force not directly associated with Chris are
expected along the North Carolina coast and over Pamlico and
Albemarle Sounds during the next day or so.


NEXT ADVISORY

Next complete advisory at 1100 AM EDT.
