Drought was not only a concern in our area, it encompassed much of the middle of the country. This including a long stretch of the Mississippi River, which experienced record/near record low levels for the second year in a row. Dredging was ongoing to help widen/deepen the river channel and keep barge traffic moving. Meanwhile, low flow was allowing salt water from the Gulf of Mexico to make headway into the river. This was threatening the fresh water supply in portions of Louisiana.

 

In the picture: Flooding rain was in the forecast (from the Weather Prediction Center) on 09/29/2023 in New York, NY and surrounding locations.
 

Drought was not an issue in New York, NY. On the 29th, a whopping 8.05 inches of rain dumped at Kennedy Airport. This was the highest total on record locally in September. Flooding was extensive (affecting homes, businesses, and schools), and a state of emergency was declared. A medical center was evacuated. Highways and numerous roads were closed due to high water. Railway and subway services were suspended and flights were cancelled.
