500 AM AST Wed Sep 26 2018

Infrared satellite imagery during the past several hours indicates
that deep convection has increased and become better organized near
the center of the remnants of Kirk. In addition, two earlier ASCAT
scatterometer passes between 0000-0100Z indicated that the low-level
center had become a little better defined, and that the inner-core
wind field had contracted, now with a radius of maximum winds (RMW)
of about 40 nmi. Given the continued increase in the amount and
organization of the deep convection, advisories have be re-initiated
on Tropical Storm Kirk. The two ASCAT passes showed peak winds of 38
and...

Tropical Weather Outlook

200 AM EDT Wed Sep 26 2018

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

A weak low pressure system located about 100 miles south-southwest

of Cape Hatteras, North Carolina, is producing disorganized shower

activity, mainly to the east of the center. Strong upper-level winds

are expected to increase further over the system today, and the

chances for tropical cyclone formation are decreasing. The low is

forecast to move north-northeastward along or near the North

Carolina coast later this morning, and it could produce scattered

showers and dangerous surf and rip currents across eastern North

Carolina as it passes by. The low is expected to move northeastward

and mer...

Leslie has become a post-tropical cyclone. Conventional and
microwave satellite imagery show that Leslie's surface circulation
has become elongated along an intruding baroclinic zone indicated
by a recent 1158 UTC ASCAT-A pass. Any deep convection appears to
be developing due to dynamic forcing. A rather large stratocumulus
cloud shield and associated cooler, stable air is quickly advecting
into the area as well. The initial intensity is maintained at 30 kt
for this last advisory.

Leslie is forecast to strengthen during the next couple of days due
to baroclinic processes. The official forec...
