Why This Virginia Coastal Storm Isn’t Tropical -- And Why It Still Packs a Punch

Rain is coming down, tides are running higher than normal, and gusty winds are rattling the coast of Virginia. With conditions like this, it’s easy to wonder if we’re dealing with a tropical system. But here’s the key: this is not a tropical cyclone. Instead, it’s a regular mid-latitude storm system -- a coastal low with very different characteristics. While it may not carry the name “tropical storm” or “hurricane,” it can still bring serious impacts like flooding, erosion, and power outages.
Tropical Cyclone vs. Non-Tropical Cyclone: What’s the Difference?
Tropical cyclones -- think tropical storms and hurricanes -- have very specific characteristics:
Warm-Core System: Fueled by warm ocean waters, concentrating that heat energy near the center.
Symmetrical Shape: Often look like a well-organized pinwheel on satellite, with bands spiraling evenly around the eye or center.
Strongest Winds Near the Center: The most intense winds are tightly wrapped around the core of the storm.
This coastal system off Virginia is very different:
Cold-Core System: Not feeding off warm ocean water, but driven by temperature differences in the atmosphere.
Attached to Fronts: Connected to frontal boundaries (the dividing lines between warm and cold air masses).
Asymmetrical Structure: Lopsided, not a neat circular storm.
Strong Winds Away from the Center: The strongest gusts are spread out, not confined to a compact core.
So while it may look like a strong storm hugging the coastline (and it is!), it’s not tropical in nature. That’s why you won’t hear it called a “tropical....” by the National Hurricane Center.
What to Expect from This Coastal Storm
Just because it’s not tropical doesn’t mean it won’t pack a punch. This storm is still bringing plenty of impacts to Virginia and surrounding states:
Heavy Rain: Widespread rainfall of 2 to 4 inches (with localized higher amounts) is possible in southeastern Virginia and northeast North Carolina. Localized flooding is a concern, especially in poor-drainage areas.
Coastal & Tidal Flooding: Persistent northeast winds are pushing water into the Chesapeake Bay and tidal rivers, leading to flooding during high tide cycles. You can track the latest tidal levels for Hampton Roads here: NOAA Sewells Point Hydrograph.
Strong Winds: Inland areas may see gusts of 25–30 mph, while the coast and southern Chesapeake Bay could experience 35–45 mph gusts. These winds can knock down tree limbs, cause minor power outages, and make travel difficult on bridges.
Beach Erosion: Pounding surf and high water levels will continue to erode beaches, especially along the Eastern Shore and Outer Banks.
Cooler Temperatures: With clouds, rain, and northeast winds, high temperatures will stay well below normal (which is 81°F), making it feel like a raw and unsettled couple of days.
What You Can Do
Even though this storm isn’t tropical in nature, the impacts can still affect your daily life. Here are a few quick preparedness tips to stay safe:
Stay Informed: Keep up with the latest updates from the National Weather Service, local TV stations and local officials.
Watch the Water: If you live near the coast or tidal rivers, monitor high tide cycles and be ready to move vehicles or belongings to higher ground.
Secure Outdoor Items: Gusty winds can easily turn patio furniture, trash cans, and decorations into flying hazards. Bring them inside.
Drive with Caution: Heavy rain and standing water can make roads slick and dangerous. Never drive through flooded roadways. The National Weather Service says #TurnAroundDontDrown for a reason!
Have a Backup Plan: Keep flashlights, batteries, and chargers handy in case of power outages.
Bottom Line: You don’t need a tropical cyclone for significant impacts. Being prepared for any strong coastal system helps keep you, your family, and your property safe.
