Hurricane Isaias 2020

Start Date

August 3, 2020

Overview

The NASA Earth Applied Science Disasters Program has activated for Hurricane Isaias to provide support to the Caribbean Disaster Emergency Management Agency and US Southern Command. 

Tropical Storm Isaias formed in the eastern Caribbean the evening of Wednesday, July 29, 2020, bringing heavy rainfall and winds to Puerto Rico and the Dominican Republic before developing into a Category 1 hurricane as it approached the Bahamas early on Friday, July 31. Isaias weakened on Saturday afternoon to a tropical storm as it continued up the eastern coast of Florida. Tropical Storm Isaias is anticipated to strengthen to a hurricane prior to making landfall in the Carolinas the evening of August 3 and is projected to then gradually weaken as it continues up the eastern seaboard.

The Disasters Program is investigating available imagery through the following NASA-funded program ROSES projects. These projects will potentially provide damage mapping, flood risk modeling, landslide mapping, and flood mapping: 

-    A.37 Global Rapid Damage Mapping System with Spaceborne Synthetic Aperture Radar (SAR) Data – damage mapping 
-    A.37 Advancing Access to Global Flood Modeling and Alerting using the Pacific Disaster Center (PDC) DisasterAWARE Platform and Remote Sensing Technologies – flood risk modeling
-    A.37 Enabling Landslide Disaster Risk Reduction and Response throughout the Disaster Life Cycle with a Multi-scale Toolbox
-    A.50 Group on Earth Observation (GEO) Work Programme Global Rapid Flood Mapping Project

The team at NASA's Johnson Space Center in Houston has submitted a targeting request to the International Space Station for astronaut photography of the storm to be shared, if available. The Disasters Program intends to also reach out to U.S. stakeholders in the potentially affected areas.

In response to Tropical Storm/Hurricane Isaias, the NASA Earth Applied Sciences Disasters program area created maps showing areas of likely flooding and damage from the July 2020 storm in The Bahamas and Dominican Republic. This Flood Proxy Map (FPM) shows areas that are likely flooded (shown by light blue pixels of 30 m in size) in Grand Bahama, The Bahamas due to heavy rains brought by Tropical Storm Isaias. This map should be used as a guidance to...
