Delaware will need to start shoveling again this weekend, especially in Sussex County.

A nor’easter will start moving up the coast late this week and interact with the cold air hitting the eastern part of the country, potentially causing a bomb cyclone. The storm, named Winter Storm Gianna by The Weather Channel, is still hard to predict as specific details remain uncertain.

According to the National Weather Service’s 4 p.m. update, there is confidence a coastal storm will impact parts of Delaware this upcoming weekend with strong winds and coastal flooding. However, it’s still too early to determine other impacts such as snowfall.

What is a bomb cyclone?

According to the National Oceanic and Atmospheric Administration, a bombogenesis, or bomb cyclone, is a mid-latitude cyclone that rapidly or explosively intensifies over a 24-hour period. The storm’s central pressure usually has to drop 24 millibars in 24 hours.

Also known as a winter hurricane, the storm is capable of producing blizzard conditions, heavy rains and strong winds.

What is a nor’easter?

According to the National Weather Service, a nor’easter is a strong low-pressure system that affects the Mid-Atlantic and New England states. They produce heavy snow, rain, and tremendous waves that can cause beach erosion and structural damage. Wind gusts associated with these storms can exceed hurricane-force intensity.

A nor’easter gets its name from the northeasterly winds blowing in from the ocean.

How to prepare for winter weather

Here are a few tips to prepare for the cold weather.

• Stock up on snow removal supplies. Add rock salt or ice melt, space heaters and snow shovels to your snow preparation arsenal.
• Make sure your snowblower is working. There’s nothing worse than having heavy snow and finding out your snowblower isn’t working. Before the storm hits, do a test run or take it in for a tune-up.
• Clean the gutters. Remove all dead leaves and other debris so that your gutters can do what they’re intended to do – collect water from the roof and channel it down to the ground.
• Inspect the roof. Repair or replace any damaged shingles or hire someone to do it for you.
• Trim tree branches. Cut or trim back any trees that are close to your house.
• Add more insulation. Call in a pro to check your insulation and add more where necessary.
• Seal up cracks. Inspect doors and windows for drafts and seal up any openings to avoid the loss of heat and warm air.
• Insulate your pipes. Frozen pipes can burst, flooding your home and yard.
