Wind, rain expected as Tropical Storm Isaias heads up Atlantic coast

August 3, 2020

The entire state of Delaware was moved into a Tropical Storm Warning Aug. 3 by the the National Oceanic and Atmospheric Administration National Hurricane Center. The storm is expected to begin early morning Tuesday, Aug. 4, bringing up to 6 inches of rain and wind gusts up to 73 mph. The greatest impacts are expected early Tuesday morning into Tuesday night, officials said.

Heavy rainfall and flash flooding are the biggest threat to the Cape Region followed by wind damage and the threat of tornadoes, according to the National Weather Service's report 7 a.m., Aug. 3.

“Wind gusts to near hurricane strength are possible near the coast,” officials said.

Along the Delaware coast, a 1 to 3 foot storm surge is expected. Some river flooding is possible, but it not expected along the main stem of the Delaware River.

“We have increased confidence in the track and intensity of Isaias, and expect areas of significant flash flooding,” the National Weather Service stated. “We are also more confident of strong winds especially near the coast. There remains some uncertainty with details, such as how far inland tropical storm force winds will extend.”

Rain and wind may down trees and power lines leading to potentially extended power outages, said the Delaware Emergency Management Agency Emergency Operations Center, which encourages residents and visitors to prepare now. These include:

  • Secure loose outdoor items such as patio furniture and grills. 
  • Clear drains around your house
  • Ensure that you have an emergency plan, including where you could go if you need to leave your home. 
  • Have a plan for how to stay cool if the power goes out. 
  • Create an emergency kit with items such as non-perishable food, water, and extra medications, to sustain each member of your family plus pets for up to 7 days. 
  • Make sure to include extra cloth face coverings, hand sanitizer, soap, and disinfecting wipes due to COVID-19.
  • Also ensure that your electronic devices are charged and that you have a backup battery bank. 
  • Finally, stay informed by monitoring the DEMA social media pages, local officials, and local weather.  To sign up for emergency alerts go to, and for preparedness tips:
