Significant Coastal Storm Expected To Bring Heavy Rains, Flooding And Damaging Winds To Delaware

In anticipation of an intensifying coastal storm this weekend, the Delaware Emergency Management Agency (DEMA) urges residents to monitor and prepare by following National Weather Service (NWS) reports and all subsequent guidance from local officials.

The NWS has announced a Coastal Flood Watch, Storm, and High Wind Watch from Sunday, Oct. 12, through the evening of Monday, Oct. 13, for portions of Delaware and across Atlantic coastal waters and the lower Delaware Bay.  

There is an increasing likelihood this storm could develop into a significant to severe weather event, potentially resulting in moderate to major coastal flooding, excessive rainfall between 1 and 5 inches along coastal and bay areas, strong damaging winds, and wind gusts of nearly 60 mph. Inland wind gusts and flooding in urban areas may occur as well. Along with this, there remains the potential for storm and wind-related tree damage and power outages. Dangerous marine and beach conditions include gale- and storm-force winds across all marine zones with very dangerous surge. Strong rip currents, beach erosion and dune breaching may also occur. The storm could result in dangerous conditions including roadway flooding, impassable roads, possible inundation of structures and the possibility for evacuations.

“We’re asking Delawareans to follow local directives to remain safe through the developing storm,” said DMA Director A.J. Schall. “Take steps now to check your emergency kit, to clear gutters and secure outdoor furniture, to set aside some cash in case of loss of power, and to avoid nonessential travel during periods of heavy rains. We’re urging residents to sign up for the Delaware Emergency Notification System by visiting de.gov/dens to receive critical alerts, and to monitor weather reports through the weekend.”

Citizens should stay informed by listening to emergency radio stations and by following trusted local agencies’ social media accounts and credible news sources for information and possible protective actions. Staying informed also means understanding one’s homeowner's insurance policy to determine an appropriate level of coverage including flood insurance from FEMA as needed. Go to preparede.org/stay-informed and floodsmart.gov for more information.
