Marine Weather and Tide Forecast for Rest Haven, GA

SHORT TERM
(Today through Thursday)
Issued at 320 AM EDT Wed Jul 22 2026

There are a couple of primary features of note across the region this morning. The first is lopsided Tropical Storm Bertha, currently situated off the Gulf coast of Alabama and struggling within an environment of strong wind shear as it continues westward. Secondly, a cold front will push southward into the Tennessee Valley today, becoming the primary weather maker for us through the short term.
While Bertha will never have any direct impact, deep tropical moisture associated with the system (characterized by PWATs well over 2" and near daily climatological maximums)
will be shunted north-northeastward through the day today as the front approaches. This will initially lead to increased coverage of scattered diurnal showers and thunderstorms this afternoon and evening, any of which will be capable of locally heavy rainfall.

The focus overnight then turns to the front as it sags into far north Georgia. Forward progression will begin to slow, and CAMs continue to indicate the potential for training showers and thunderstorms across far north Georgia tonight into Thursday morning within the frontal zone. While widespread flash flooding is not expected, given the very moist airmass, localized flash flooding will be possible in far north Georgia tonight into Thursday morning.
As such, a "Slight" Day 1 Excessive Rainfall Outlook from WPC highlights this potential.

Heading into the day Thursday, the front becomes more or less stationary across north Georgia. The band of very high 2+" PWATs interacting with the continued forcing of the frontal boundary will lead to continued locally heavy rainfall concerns on Thursday.
Again, while widespread flash flooding is not currently anticipated, localized flash flooding will remain a distinct possibility, particularly where convective training occurs. The "Slight" Risk for Excessive Rainfall expands further across all of north Georgia as a result.

The positive attribute of the presence of the front and increased convection will be gradually downward-trending temperatures in north Georgia from today into Thursday as highs step down slightly from the lower 90s to the mid-to-upper 80s. Even so, plenty of 90s will remain in place across Middle Georgia each day where rainfall coverage will be less abundant, and heat index values will still peak above 100 for many.

LONG TERM
(Thursday night through Tuesday)
Issued at 320 AM EDT Wed Jul 22 2026

Slightly cooler, slightly less humid conditions remain expected Thursday through Sunday with highs generally ranging from the low 80s north of the Atlanta metro to the low 90s across our far southeastern counties, and lows ranging from the upper 60s north to lower 70s southeast. The most noticeable relief from our recent heat will definitely be felt across the north Georgia mountains, with less of a real pattern change as you head south. Variable areas of even cooler conditions will be possible tied to thunderstorms and attendant cloud cover. The heat and humidity look to return in earnest early next week, with high temperatures rising back into the mid to upper 90s and heat index values reaching 100 north to 110 southeast. If this forecast holds, Heat Advisories may be needed for portions of the CWA as early as Monday.

Meanwhile, the weak cool front responsible for the modest relief late week into the weekend is forecast to stall/wash out across the area, and combine with additional moisture from Tropical Storm Bertha (or its remnants) to continue to support increased daily coverage of showers and thunderstorms. We now carry PoPs of 50-80% across large swaths of the CWA each day through Saturday. Localized flash flooding will continue to be a primary concern through this period with model forecast soundings suggesting PWATs of 2.00 to 2.50 inches and relatively weak steering flow at times, with this risk locally enhanced in locations that become saturated from a previous day's storms. WPC currently carries a Marginal Risk to Slight Risk of excessive rainfall across the entire CWA Thursday, with a Marginal Risk continuing for most areas Friday and Saturday.
Gusty winds will remain possible with the stronger storms as well.
Storm coverage will return to a more typical isolated to scattered posture early next week as the heat returns.
