NWS National Hurricane Center Miami FL
200 AM EDT Sun Jul 3 2022

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

Active Systems:
The National Hurricane Center is issuing advisories on recently 
downgraded Tropical Depression Colin, located near the southeastern 
coast of North Carolina.

Central Caribbean Sea:
Recent satellite-derived wind data indicate that a tropical wave 
over the central Caribbean Sea is producing winds to near gale 
force just south of Hispaniola, and disorganized shower and 
thunderstorm activity stretches across the Virgin Islands, Puerto 
Rico, Hispaniola, and the adjacent waters of the Caribbean Sea.  
Despite these conditions, development of the wave is not expected 
while it moves westward at about 20 mph into an area of stronger 
upper-level winds over the western Caribbean Sea.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...near 0 percent.

Public Advisories on Colin are issued under WMO header WTNT33 KNHC 
and under AWIPS header MIATCPAT3.  Forecast/Advisories on Colin are 
issued under WMO header WTNT23 KNHC and under AWIPS header

WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:
 
The Tropical Storm Warnings for the North Carolina coast and the

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:
 
There are no coastal watches or warnings in effect.
 
 
DISCUSSION AND OUTLOOK
----------------------
At 1100 PM EDT (0300 UTC), the center of Tropical Depression Colin
was located near latitude 34.4 North, longitude 77.8 West. The
depression is moving toward the northeast near 7 mph (11 km/h). A
slightly faster northeast to east-northeast motion is expected
during the next day or so. On the forecast track, the center of
Colin or it remnants is expected to move northeastward along or
just inland of the North Carolina coast through Sunday afternoon.
 
Maximum sustained winds have decreased to near 35 mph (55 km/h)
with higher gusts.  Additional weakening is likely, and Colin is
expected to degenerate to a remnant area of low pressure later
tonight or on Sunday.  The system is expected to dissipate
completely Sunday night or Monday.
 
The estimated minimum central pressure based on surface
observations is 1014 mb (29.95 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND:  Gusts to tropical-storm force in squalls are possible across
portions of coastal North Carolina tonight.
 
RAINFALL:  Colin will continue to produce locally heavy rainfall
across coastal portions of North Carolina through Sunday morning,
where an additional 1 to 2 inches of rainfall is possible. This
rainfall may result in localized areas of flash flooding.
 
SURF:  Swells generated by Colin are affecting portions of the
North Carolina coast. These swells could cause life-threatening
surf and rip current conditions.  Please consult products from your
local weather office.

Issued at 1100 PM EDT Sat Jul 02 2022 <pre> 808 WTNT43 KNHC 030234 TCDAT3 Tropical Depression Colin Discussion Number 4 NWS National Hurricane Center Miami FL AL032022 1100 PM EDT Sat Jul 02 2022 Colin continues to become less organized, with only minimal convection currently occurring and surface observations showing that the circulation is losing definition. Offshore buoys have reported winds of 20-25 kt for the past several hours, suggesting that there are no tropical-storm-force winds left over water. Based on this, Colin is downgraded to a tropical depression, and all of the coastal warnings are discontinued. The current weakening trend is expected to continue due to increasing northwesterly vertical wind shear and dry air entrainment, and Colin is now forecast to degenerate to a remnant low pressure area within the next 12 h. The remnants are forecast to dissipate after 24 h as they merge with a frontal system over the northwestern Atlantic. The initial motion is an somewhat uncertain 055/6 kt. Colin or its remnants should continue to move generally northeastward through eastern North Carolina for the next 12-18 h, and then move out over the Atlantic before merging with the aforementioned frontal system. KEY MESSAGES: 1. Rough surf and rip currents are likely to continue along the North Carolina coast through Sunday. 2. Scattered areas of heavy rainfall may result in localized flash flooding across coastal portions of North Carolina through Sunday morning.
