Mapping the Impact of Tropical Storm Harvey

 

Tropical Storm Harvey could be a hurricane with wind speeds of at least 111 mph and is expected to hit Texas Friday. Widespread flooding is a risk for Texas and neighboring states as public safety groups and communities prepare.

Esri, the leader in spatial analytics and mapping, has created a new Hurricanes and Tropical Cyclones Story Map that identifies the potential impact of the storm through a variety maps, including:

  • Public Information Map - identifies the current and recent location of Harvey as well as forecast positions and probable track; additionally, the shaded area is called the "cone of uncertainty," the likely path of the center of Harvey.
  • Impact Summary Map - shows the storm surge by identifying locations most at risk for life-threatening inundation from storm surge; accordingly, to Esri's data, the total population at risk is 248k people, 99k households, and 10k businesses.
  • Forecast Precipitation Map – forecasts the amount of rain expected within the next 72-hour period
