.DISCUSSION...
Issued at 1216 PM CDT Mon Jul 20 2026

Tropical Depression Two which is currently located about 120 miles
south of Panama City, Florida, is expected to strengthen to a
tropical storm later today. The system is forecast to move
across the far offshore waters of Alabama and the western Florida
panhandle Tuesday into Tuesday night before exiting to the west.
Please see the National Hurricane Center for the latest on
Tropical Depression Two. A Tropical Storm Watch remains in effect
for coastal portions of Alabama and the western Florida
panhandle. A Storm Surge Watch has been issued for coastal Alabama
for storm surge heights potentially reaching 2-4 feet during
periods of high tide Wednesday and Thursday mornings. Storm surge
heights of 1-3 feet will be possible along coastal portions of the
western Florida panhandle. Have issued a High Surf Advisory for
surf heights building to around 10 feet across beach areas. The
High Surf Advisory begins at 1 pm Tuesday for the western Florida
panhandle and at 7 pm for Alabama and continues until 6 am
Thursday, by which time surf heights should have sufficiently
subsided. A High Risk of rip currents comes in effect this evening
and continues until dropping to a moderate risk on Friday.

There is a marginal potential for some localized flooding concerns
mainly over the coastal areas through much of the week. Will have
slight chance to chance pops for the southern portion of the area
mainly this evening then for Tuesday have gone with likely to
categorical pops east of I-65 tapering to low pops across
interior southeast Mississippi and interior southwest Alabama. As
the tropical system continues off to the west on Wednesday, will
have chance to likely pops roughly along and east of I-65 with
slight chance pops elsewhere. For Thursday on into Sunday, have
gone with chance to likely pops each day as abundant deep layer
moisture looks to be in place in an otherwise summertime pattern.
A Heat Advisory remains in effect for southeast Mississippi until
7 pm Tuesday for heat index values up to 110. Elsewhere, heat
index values of 100-107 are anticipated. It`s possible that the
Heat Advisory may need to be extended into portions of southwest
Alabama on Tuesday as heat index values reach criteria of 108 in a
few spots, but this looks limited in scope at this point. /29
