2019 East Coast floods (Blackford)

the 2019 East Coast flood was a prolonged period of flooding caused by a combination of snowmelt, several storm systems bringing heavy rain as well as Tropical Depression One, which moved just barely off the coast of the Carolinas on April 28 while approaching possible tropical storm status.

The first floods of the event were recorded on February 26, 2019 in Delaware, although the states of North and South Carolina would be the worst effected regions of the flooding event.

Meteorological history
On February 19, 2019, Winter Storm Xena moved into the northeastern United States, bringing snowfall totals as high as 25 inches across parts of Delaware, with isolated totals in the mountains of North Carolina reaching 40 inches or higher.

By February 21, Xena had cleared the northeast, after producing a maximum snowfall total of 47 inches in the mountains of McDowell County, North Carolina.

On February 24, the Weather Prediction Center (WPC) issued a Day 3 slight risk of flooding for the areas effected by Xena, as temperatures were anticipated to increase from 15-20°F across most of the region to around 40-45°F over February 25 and 26, ending the winter season across some areas.

This was increased to a moderate risk on February 25, with some rain now also anticipated to add on to the snowmelt. Temperatures reached 50°F across portions of Delaware on February 26, and snowmelt began that morning.

The WPC issued a high risk of flooding for February 26 due to the fact that as much as 20 inches of snow was located on the ground across most of the area, and a additional 5-8 inches of rain was also possible (which warranted a moderate risk of excessive rainfall for the same region).

Another moderate risk of flooding was in place across the Carolinas due to temperatures approaching 55°F across elevations higher than 1,000 feet, which could cause moderate to severe flash flooding in spots.

Late February flood event
On February 26, rapid snowmelt ensued across portions of the Mid-Atlantic as temperatures reached as high as 60°F in isolated spots. This snowmelt resulted in rivers cresting at moderate to severe flood stage on February 27 and 28 across Delaware and Maryland.

One person was swept away from flood waters near Alexandria, Virginia on February 27, as the area had seen over 10 inches of rain as well as upwards of 30 inches of snow still on the ground (which had now melted into over a foot of water on the ground).

Flash flood warnings were put out through the flood event, mainly across the states of Delaware and Maryland, with the town of Sussex Woods, Delaware being put under a mandatory evacution order on March 1 due to catastrophic flooding.

The rivers began to fall below flood stage on March 2-5, and the flood event mostly came to a end by March 7, however some rivers across the region wouldn't fall below minor flood stage until late June.
