According to NOAA's Spring Outlook released last week, rivers in western New York and eastern New England have the greatest risk of spring flooding in part because of heavy snowpack coupled with possible spring rain. The NOAA's Spring Outlook identifies areas at risk of spring flooding and expectations for temperature, precipitation and drought from April through June. The outlook provides emergency managers, water managers, state and local officials, and the public with valuable information to help with flood preparation and protection. Spring Flood Risk Eastern United States Across eastern New England and western New York, record snowfall and unusually cold temperatures in February through early March retained a significant snowpack, raising flood concerns.

Let's take a look at the top 15 countries with the most people exposed to river flooding, as described in an article from the World Resources Institute : Aqueduct Global Flood Analyzer A new online tool quantifies and visualizes the reality of global flood risk. The analyzer estimates current and future potential exposed GDO, affected population and urban damage from river floods for every state, country and major river basin in the world. The tool ranked 164 countries by the number of people affected by river flooding and found that the top 15 countries account for nearly 80% of the total population affected each year.

Our Changing Climate: Rain, Snow and Runoff

Image
Across the United States as a whole, annual average precipitation increased by close to 2 inches between 1895 and 2011. In recent decades, annual average precipitation increases have been observed across the Midwest, Great Plains, the Northeast and Alaska. However, decreases have been observed in Hawaii and parts of the Southeast and Southwest. Average annual precipitation is projected to increase across the northern U.S. and decrease across the southern U.S., especially the Southwest. With the increases in precipitation comes increased flooding possibilities. BIG BAGS USA ®  is here to help with all your flood mitigation needs!
