DISCUSSION
ISSUED AT 205 PM CDT FRI OCT 2 2026
THE HIGH PRESSURE OVER THE ATLANTIC CONTINUES TO ADVECT IN
TROPICAL MOISTURE. CURRENT PWATS ARE AROUND 1.9 INCHES AND RISE TO
AROUND 2.2- 2.3 INCHES THROUGH THE DAY. THIS TREND CONTINUES INTO
THE WEEKEND THANKS TO THE REMNANTS OF HURRICANE POLO WHERE PWATS
FURTHER CLIMB TO AROUND 2.5 INCHES BASED ON ENSEMBLE MEANS. THIS
MOISTURE IS QUITE ANOMALOUS BEING WELL ABOVE THE 90TH PERCENTILE
(~1.95 INCHES) AND IS EVEN CLOSE TO THE DAILY MAX OF 2.54 INCHES
BASED ON SOUNDING CLIMATOLOGY. WITH PWATS THIS HIGH, THE
ATMOSPHERIC COLUMN WILL BE CLOSE TO FULLY SATURATED. THE
SIGNIFICANT DEEP LAYER MOISTURE AND FREEZING LEVELS OF 15,000+FT
WILL SUPPORT EFFICIENT WARM RAIN PROCESSES WITH RAINFALL RATES
TOPPING OUT AT 2-3 INCHES/HOUR.
MULTIPLE ROUNDS OF HEAVY RAINFALL ARE EXPECTED THROUGH THE
WEEKEND AND INTO MONDAY BEFORE THE DEEP MOISTURE DEPARTS. CAMS
HAVE CONTINUED TO PINPOINT AREAS ALONG THE COAST FOR THE HIGHEST
RAINFALL AMOUNTS. HREF 6-HOUR LPMMS SHOW SOME BULLS-EYES OF AROUND
4-6 INCHES ALONG THE COAST THIS EVENING AND ESPECIALLY SATURDAY
AFTERNOON INTO THE EVENING. RIGHT NOW WE ARE FORECASTING
PRECIPITATION TOTALS OF 4- 6 INCHES THROUGH MONDAY AND SOME OF OUR
FAR NORTHERN REACHES COULD ONLY RECEIVE 2-3 INCHES. SOME
LOCALIZED AREAS, ESPECIALLY ALONG THE COAST COULD RECEIVE UP TO
7-10 INCHES WHERE STORMS TRAIN OVER THE SAME AREA. WE HAVE HELD
OFF ON A FLOOD WATCH GIVEN ANTECEDENT CONDITIONS AND HIGHER FFG
THROUGH THE AREA, BUT THIS WILL CONTINUE TO BE MONITORED AS THE
EVENT PROGRESSES. NO WIDESPREAD SEVERE WEATHER IS EXPECTED WITH
THIS EVENT, BUT SOME GUSTY WINDS AND LIGHTNING ARE POSSIBLE WITH
ANY STORMS. THE GOOD NEWS IS THAT WHILE IT IS VERY MOIST AND
RAINY, TEMPERATURES ARE AT OR BELOW NORMAL THROUGH THE WEEKEND AS
THE RAINFALL AND CLOUD COVERAGE KEEPS HIGHS MOSTLY IN THE LOW 80S.
THE PLUME OF DEEP TROPICAL MOISTURE (2+ INCH PWATS) LASTS INTO THE
BEGINNING OF NEXT WEEK KEEPING THE INCREASED RAIN CHANCES INTO AT
LEAST MONDAY. A COLD FRONT THEN SWEEPS THROUGH THE AREA AND
DECREASES RAIN CHANCES AROUND TUESDAY AND INTO LATE NEXT WEEK.
TEMPERATURES WILL DECREASE AND THE DRIER AIR WILL BE VERY WELCOMED
AFTER THIS WET PERIOD. THE FRONT DOES COME WITH INCREASING WINDS
WHICH WILL HAVE MARINE WINDS NEAR ADVISORY LEVELS, HIGHER WAVE
HEIGHTS, AND AN INCREASED RIP CURRENT RISK AGAIN.
..COASTAL FLOODING
MINOR COASTAL FLOODING CONTINUES TO BE A CONCERN SATURDAY MORNING
AND POTENTIALLY SUNDAY MORNING. LOCAL TIDE GAUGES SHOWED VERY
CLOSE OR EXCEEDED THRESHOLDS THIS MORNING AND A SIMILAR SETUP
LOOKS TO BE TRUE FOR SATURDAY MORNING DURING THE PRE-DAWN HOURS
WHEN THE HIGH TIDE COMBINES WITH PERSISTENT ONSHORE FLOW. MOST
AREAS APPROACH OR EQUAL OUR 2.0 FEET MHHW THRESHOLD (2 FEET ABOVE
NORMALLY DRY GROUND) SO WE OPTED TO ISSUE A COASTAL FLOOD ADVISORY
FOR ALL COASTAL AREAS FROM MIDNIGHT TO 8AM SATURDAY. EXPECT SOME
MINOR INUNDATION FOR TYPICAL TROUBLE SPOTS LIKE DAUPHIN ISLAND AND
FORT PICKENS AND SPLASHOVER ON THE CAUSEWAY.
..BEACH FORECAST
HAZARDOUS BEACH CONDITIONS CONTINUE WITH ALL AREA BEACHES FLYING
RED FLAGS TODAY. THE RIP CURRENT RISK CONTINUES TO BE HIGH FOR ALL
BEACHES IN SOUTHERN ALABAMA AND THE NORTHWEST FLORIDA PANHANDLE.
THE HIGH RISK CONTINUES TO SUNDAY NIGHT THEN DROPS TO A MODERATE
THROUGH TUESDAY BEFORE INCREASING AGAIN AROUND WEDNESDAY NIGHT.
INCREASED SURF UP TO 3-4 FEET CONTINUES INTO THE BEGINNING OF NEXT
WEEK AND BY MID WEEK MAY FURTHER INCREASE TOWARDS HIGH SURF
ADVISORY CRITERIA.

ISOLATED LIGHT RAIN SHOWERS LINGERING OFFSHORE. SHOWER AND
THUNDERSTORM ACTIVITY WILL THEN INCREASE IN COVERAGE ALONG THE
COAST EARLY SATURDAY MORNING AND SPREAD INLAND THROUGHOUT THE DAY,
