Millions across southeast Texas and parts of Louisiana will remain under flash flood watches into Thursday because of torrential rain that has swept through the region, triggering power outages and reports of localized damage.
NEW YORK—Following a City Council vote, Mayor Bill de Blasio today announced that a major package of zoning rules will now help to protect homes and businesses in New York City’s vast floodplain from climate change. The package of zoning rules, known as Zoning for Coastal Flood Resiliency (ZCFR), helps buildings better withstand and recover from major disasters and sea level rise, which could lead to lower insurance costs.
Houston’s weather has gotten hotter and wetter, according to the latest data from the National Oceanic and Atmospheric Administration. It mirrors a general trend across the country as the planet warms.
Every 10 years, NOAA updates what it considers “normal ” weather across the country. The so-called “new climate normals” are based on rolling averages of temperature and precipitation from the past 30 years, with the latest update reflecting weather data from 1991-2020. The previous normals were based on data from 1981-2010.
when it rains, it pours.
Today’s rainstorms give new meaning to this age-old expression.
Extreme precipitation has increased in nearly every region of the mainland United States since the start of the 20th century, according to the Fourth National Climate Assessment, a comprehensive scientific report about climate change in the U.S.
Habitats, such as coral reefs, can mitigate increasing flood damages through coastal protection services. We provide a fine-scale, national valuation of the flood risk reduction benefits of coral habitats to people, property, economies and infrastructure. Across 3,100 km of US coastline, the top-most 1 m of coral reefs prevents the 100-yr flood from growing by 23% (113 km2), avoiding flooding to 53,800 (62%) people, US$2.7 billion (90%) damage to buildings and US$2.6 billion (49%) in indirect economic effects. We estimate the hazard risk reduction benefits of US coral reefs to exceed US$1.8 billion annually.
Flooding is a growing problem across the U.S., from increasingly frequent and intense hurricanes and tidal flooding to seasonal inland events driven by more and heavier rains. As these disasters exact a mounting toll on communities, many policymakers and other stakeholders are asking: How can federal policy support local flood resiliency efforts?
King tide floods affected many locations along the East Coast this weekend, including Charleston. This type of flooding, often called sunny day flooding, occurs during the highest astronomical tides of the year. Dr. Kirstin Dow, a professor at the University of South Carolina, says that king tide floods are normal, but they are also are getting worse.
There’s stark evidence of the problem near the town of Truth or Consequences, about 100 miles north of the Mexican border. The century-old Elephant Butte Dam was constructed along the Rio Grande to provide power and irrigation to south-central New Mexico and West Texas, and the resulting reservoir spans 60 square miles.
The storm came from the southwest, loaded with moisture from the Gulf of Mexico. Gray clouds moved in with little warning, drizzling at first. Then just before noon Friday the skies opened up, unleashing a storm of disruption.
