.DISCUSSION...
KEY MESSAGE 1...Dangerous heat expected through early next week.
Mid-level high pressure will generally prevail across the region
aiding in above normal temperatures through the period. High
humidity will help push heat indices into Heat Advisory range (105-
109 degrees) for most each day and even into Heat Warning range
(110+ degrees) for some (mainly across the coastal Counties where
dewpoints should be greatest). However, it is worth noting that
forecast confidence regarding heat indices remains lower than
normal, especially this weekend, as there is some uncertainty
regarding temps/dewpoints/rain/cloud coverage.
Remember, heat is the #1 weather-related cause of death so everyone
is encouraged to take proper precautions. Check out our heat page
(weather.gov/ilm/heat) for the latest heat forecasts and safety
info.
KEY MESSAGE 2...Minor coastal flooding expected through the rest of
the week, especially along the lower Cape Fear River.
Astronomical influences from the new moon will cause elevated tide
levels thru late week. Minor coastal flooding is expected along the
coast and along the lower Cape Fear River, especially during the
evening high tides through today. Along the lower Cape Fear River,
minor coastal flooding is also possible during the morning high
tides.

.MARINE...

most of the period, although a weak front should stall over or near
