Who should be worried about coastal flooding?
Coastal flooding is defined as the flooding of normally dry, low-lying coastal land, primarily caused by severe weather events along the coast, estuaries, and adjoining rivers (NOAA). You might not currently live in a coastal area but for anyone who travels or visits these areas it is important to understand this phenomenology. Coastal flood events are some of the more frequent, costly, and deadly hazards that can impact coastal communities. Coastal flooding can result from a ‘storm surge,’ water pushed ashore by severe weather; it can also be caused by unusually large waves driven by winds of swells. Under certain conditions, coastal flooding can be caused or increased by rainfall over land that does not quickly drain into the sea. Coastal floods are extremely dangerous, and the combination of tides, storm surge, and waves can cause severe damage.
So whether you currently live in a coastal area or are planning a vacation to one, remember to stay aware of severe weather in the area…to include tropical cyclones! Remember even on vacation you should always be prepared!
Globally we are experiencing flooding in the Americas, Europe, Africa, and Asia. We have chosen to take a closer look at recent flooding in Beijing, China, and Jos, Nigeria; both areas were hit extremely hard over the last week.
Precipitation & Flooding: Beijing, China
The city of Beijing, China, has been severely impacted by record amounts of heavy rainfall. The heavy rains resulted in severe flooding. (ReliefWeb) Overall, 77 people were reported killed in Beijing in the storm that destroyed 8,200 homes and submerged at least 84 vehicles along a major highway. Rain-triggered mudslides have hampered efforts to conduct rescues and retrieve bodies. (ReliefWeb) Heavy rains, which began on July 20, have resulted in at least 111 additional deaths, beyond Beijing, in outlying provinces. (ReliefWeb). PDC will continue to monitor official sources for reports of the impact of the flooding.
The latest forecast for Beijing, China shows areas of continued precipitation which may continue to hamper response operations. The remnants of Tropical Storm Vicente are expected to move through southern China over the next few days.
Precipitation & Flooding: Jos, Nigeria
A dam in the city of Jos, Nigeria, overflowed on July 23 during a heavy rainstorm, resulting in the deaths of 35 people. Many of the victims were children. Relief efforts are underway to assist the 700 people displaced. The storm is the latest of several flood disasters to affect the country this year. The largest cities in Nigeria are overcrowded, with many residents living in haphazardly constructed communities, served by poorly maintained drainage systems. (ReliefWeb)
The latest forecast for Jos, Nigeria shows areas of continued precipitation.
PDC is also currently monitoring flooding events in: Australia, Canada, England, Georgia, Guatemala, Honduras, India, Indonesia, Nepal, Nicaragua, Philippines, West Africa and Sudan.
