CHANGES WITH THIS ADVISORY:
None
SUMMARY OF WATCHES AND WARNINGS IN EFFECT:
A Tropical Storm Warning is in effect for...
* South Santee River, SC to Surf City, NC
A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.
For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.
DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Tropical Storm Chantal was
located near latitude 34.0 North, longitude 79.2 West. Chantal is
moving toward the north-northwest near 8 mph (13 km/h). A turn
northward and then northeastward is anticipated over the next 24
hours. On the forecast track, the center of Chantal is expected to
move further inland over South Carolina and then North Carolina
through the day today.
Maximum sustained winds have decreased to near 40 mph (65 km/h)
with higher gusts. Additional weakening is expected as Chantal
moves inland, and the system is forecast to degenerate into a
trough of low pressure on Monday.
Tropical-storm-force winds extend outward up to 80 miles (130 km)
mainly over water to the southeast of the center. In the past
couple of hours, a sustained wind of 33 mph (54 km/h) with a gust to
47 mph (76 km/h) was reported at Coastal Research and Monitoring
Program buoy just off Sunset Beach, North Carolina.
The estimated minimum central pressure based on nearby surface
observations is 1005 mb (29.68 inches).
HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Chantal can be found in the
Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO
header WTNT43 KNHC.
WIND: Tropical storm conditions will continue within portions of
the warning area this morning.
RAINFALL: Tropical Storm Chantal is expected to produce heavy
rainfall across portions of northeastern South Carolina today and
across portions of North Carolina through Monday. Storm total
rainfall of 2 to 4 inches, with local amounts up to 6 inches, is
expected. This would result in an elevated risk for flash flooding.
For a complete depiction of forecast rainfall and flash flooding
associated with Tropical Storm Chantal, please see the National
Weather Service Storm Total Rainfall Graphic, available at
hurricanes.gov/graphics_at3.shtml?rainqpf
TORNADOES: Isolated tornadoes will be possible today across portions
of eastern North Carolina and extreme northeastern South Carolina.
SURF: Chantal is expected to bring life-threatening surf and rip
currents to portions of the coast from northeastern Florida to
the Mid-Atlantic states during the next day or so.

Tropical Storm Chantal Discussion Number 7
NWS National Hurricane Center Miami FL AL032025
500 AM EDT Sun Jul 06 2025
Before the Air Force Reconnaissance plane departed Chantal this
morning, their final leg observed 700 mb flight level winds of 59 kt
and a dropsonde estimated pressure down to 1002 mb. Near the same
location as those peak flight-level winds, NWS Doppler Radar
velocities from Wilmington showed persistent 65-70 kt inbound values
at 3-5 thousand feet. These data points were the basis for
increasing Chantal's winds to 50 kt at the 06 UTC intermediate
advisory. Since that time, the structure of the tropical storm on
radar has degraded and the exact center has been difficult to pin
down, but appears to have made landfall near Litchfield Beach, South
Carolina at approximately 08 UTC. The initial intensity has been
lowered to 45 kt for this advisory given the degradation in
appearance now just after landfall and the decreasing Doppler radial
velocities.
Chantal is estimated to now be moving north-northwestward, at 345/7
kt. A turn northward and then northeastward is anticipated by the
end of today as the cyclone rounds the westward side of a mid-level
ridge located off the U.S. East Coast. The latest NHC track forecast
is shifted just a bit eastward, mostly based on the initial
position, but falls in line closely to the prior forecast track in
24-36 h. Weakening has already started as Chantal moves inland.
Weakening should continue as the full circulation moves inland, with
Chantal likely weakening back to a tropical depression later today.
The majority of the global and hurricane-regional models then show
the circulation opening up into a trough after 36 h, though its
likely Chantal's remnant moisture will continue onward into the
Mid-Atlantic and Northeastern United States after this time period.
Chantal is expected to remain asymmetric with its strongest winds
and rainfall to the right of the landfall location.
Key Messages:
1. Tropical storm conditions are expected to continue in the warning
area through this morning.
2. Heavy rainfall across portions of northeastern South Carolina
will cause some flash flooding concerns from Tropical Storm Chantal
today and across portions of North Carolina through Monday. Isolated
to scattered flash flooding could occur within more urbanized areas.
3. Chantal is expected to bring life-threatening surf and rip
currents along the coast from northeastern Florida to the
Mid-Atlantic states during the next day or so. Beach goers
should heed the advice of lifeguards and local officials.
