Tropical Storm Elsa is headed toward Delaware. Here's what to expect and how to prepare

Tropical Storm Elsa is on its way to Delaware and approaching fast.

The National Weather Service expects the storm to arrive in southern Delaware on Thursday night into Friday morning.

All Delaware counties should expect to be impacted by the storm, but Sussex County is under a tropical storm warning – upgraded from an earlier tropical storm watch – that's in effect due to the expected tropical-storm-force winds. This also applies to the Delaware coastline.

“The main concern we’re thinking with this storm will be heavy rainfall potential,” a National Weather Service spokesperson said.

As Elsa hits Delaware on Thursday evening, it's expected to bring with it 1 to 3 inches of rain with the potential for more in certain areas around southern Delaware. 

Moving into Friday, coastal Delaware has a 90% chance of precipitation.

Forecasters say they expect to see the storm's biggest impact Thursday night into Friday morning.

Increased rain could result in flash flooding and river flooding. With the possibility of dangerous rip currents, a high rip current risk is in effect for Delaware beaches from Friday morning through Friday evening. Forecasters also advised caution for Atlantic coastal waters and the Delaware Bay as seas are expected to build anywhere from 6 to 9 feet.

As for tornadoes, which Delaware has seen more of in the last year, the National Weather Service said the "risk is fairly small," but has issued a Thursday evening update advising the southeastern region of the state to be prepared for one and the related damage.

Even without the appearance of a tornado, residents should look out for hazardous wind impact to trees, fences, road signs, power lines and lightweight outdoor objects. Porches and roofs are also susceptible to damage from the high-speed winds brought on by the storm.

Dangerous driving conditions may also occur, especially on bridges and elevated roadways, as debris gets caught in the storm.

By the weekend, Saturday is expected to be mostly sunny while the possibility of rain and thunder loom over Sunday.

How to prepare for Tropical Storm Elsa

The Delaware Emergency Management Agency recommends planning ahead to ensure you are prepared for emergency situations such as this one.

Some of their tips include charging all electronic devices and having portable power banks handy, packing an emergency kit with enough supplies for each member of your family, and making an emergency plan in case you need to evacuate your home.

Don’t forget flashlights – and batteries.

DEMA also advised residents to make sure they have a full tank of gas, full tires and working lights ahead of the storm.

Homes can be better protected by securing all loose outdoor items, trimming trees and bushes to prevent damage, and clearing drains to prevent flooding.

In the event of a power outage, have a plan for keeping your home cool or make sure you have a generator in working condition.
