Heavy rainfall will continue to be a concern for flooding issues and some local rivers through the end of the week.
We have been locked in a soggy pattern since Sunday and during the past 48 hours a few areas have received up to 4-5 inches of rain in Nassau County and 2-3 inches in Duval.
Monday an inch of rain fell at Jacksonville International Airport nearly erasing the yearly rainfall deficit which was at 1.3″ below normal.
Now that the rainy pattern has kicked in, it could come all too fast. The stalled front lingering over north Florida for the next couple of days will focus flash flooding in our backyards until we start to dry out just in time by the weekend.
Until then, the weak steering flow and ample moisture pooling along the front will lead to more heavy rain concerns.
Tuesday’s heaviest areas will likely be along and east of the U.S. Highway 301 corridor throughout the northeast and north central FL and throughout southeast Georgia.
Other areas along and south of Interstate 10 could see localized flooding this afternoon and evening totaling another 1-2 inches. Urban areas may not drain well including locations near the St. Johns River around times of high tide at 1:42 PM Tuesday and 2:27 Wednesday.
The extra rain expected Wednesday may result in Flood Watches being issued due to all the saturated soils.
Water is rising on the South Fork of Black Creek, where it could reach Action Stage by Wednesday and Thursday.
If more rain continues then the forecast may jump higher past the flood stage later this week. So far flooding is not expected along the St. Marys River this week.
