A Broad View of Flooding in the Carolinas
The National Weather Service office in Raleigh offered a preliminary estimate that nearly 8 trillion gallons of rain fell on #NorthCarolina
from Sept 13 to 17, 2018. That led to catastrophic #flooding
across many parts of the state.
Before and after #HurricaneFlorence
swept through the Carolinas, the Operational Land Imager (OLI) on the #Landsat8
satellite observed several residential areas and major rivers. The image pair above shows the Trent River on July 14, 2017, and September 19, 2018. These false-color images use a combination of visible and infrared light (OLI bands 6-5-4) to make it easier to distinguish between flood waters and land.
reached an all-time high of 29 feet (8.8 meters) on September 17, more than twice the #flood
stage (the height at which the river will overflow and cause damage). Water levels decreased to 24 feet (7.3 meters) by September 20, but many homes, public buildings, and roads leading to the town of Trenton are full of standing water.
The Trent was one of 16 rivers that reached major flood stage in North Carolina on September 18. The majority of the rivers have started to subside but still remain in major flooding stage.
The National Weather Service reports a few rivers are still rising. The #NeuseRiver
at Kinston and a portion of the #CapeFear
River were projected to rise an additional foot by September 22.
