Hurricane Debby

September 2, 2022
Savannah saw the most August rainfall since 1995, according to National Weather Service data. The 8.31 inches of precipitation far surpassed the norm of 5.46 inches. Additionally, some parts of Savannah saw significantly more rain than others — the 8.31 inches was measured at the Savannah-Hilton Head International Airport. Hunter Army Airfield's gauge measured 14 inches of rain.

The forecast for Labor Day weekend is for several inches more rain.

The August rainfall was the most since September 2021, when Savannah recorded 9 inches of rain, including 6.66 inches in one day. The last wetter August came in 1995, when the local area was swamped by 17 inches in rain, including 12 inches in a four-day period and 5.75 inches in a single day.

Some of the models are starting to cave to a more climo track which results in much less rain. 6” will still flood Savannah to Charlestown but that’s a lot better than 24”! I’m liking the trends this morning and I believe the NHC will nudge those totals downward closer to 6-10”.
 
Final Call. 6-10” for most in the yellow (some areas 4-8”) and 12” to 24” in the pink with the greatest totals south-west of Wilmington NC into South Carolina. IMG_3252.jpeg
