Storm Surge Basics for Nokomis FL Homeowners

You are sitting in Ohio in mid September. A storm is turning toward the Gulf coast. You pull up a map, see that your Nokomis street is not right on the water, and decide the house is fine. Two weeks later someone sends you a photo of a dirty line running across your garage wall. Everything below that line is ruined.

That line is storm surge. It surprises owners more than any other hurricane hazard, because it does not behave the way people expect.

What storm surge actually is

Storm surge is an abnormal water level rise generated by a storm, over and above the predicted astronomical tide. Add the normal tide to that surge and you get storm tide. Neither figure includes the waves riding on top, which push the water higher still.

Surge is not rain flooding. Rain floods from the sky down. Surge pushes in from the Gulf, and it can travel miles inland. If your neighborhood did not get surge in the last hurricane, that does not mean it is safe in the next one.

Six things drive how high surge goes. Storm strength. How fast the storm moves. How large it is. The angle it comes in at. The slope of the sea floor. The shape of the coastline. Those last two matter here. A wide, gently sloping shelf lets water pile up higher than a steep one, and the west coast of Florida sits on a wide shelf.

Why this is worse in an empty house

Water is heavy, roughly 1,700 pounds per cubic yard. Moving water at that weight pushes on walls, lifts appliances, and pulls cabinets off their mounts.

Then the water leaves, and the real problem starts. Salt water stays in the drywall and the subfloor. If the power is out, the air conditioning is off. Humidity climbs inside a closed house. Mold follows. Shallow water in an occupied home is a cleanup. The same water in a house nobody has opened in six weeks is a much larger job.

Six things to do before the next storm

1. 1Look up your evacuation level, not your flood zone. They are different. Florida evacuation zones run A through F, and Zone A leaves first. Sarasota County has an online lookup tool. Write your level down somewhere you can find it from out of state.

1. 1Sign up for county alerts at AlertSarasotaCounty.com. Evacuation orders are issued locally. If you are not on the list, you are relying on the news or a neighbor to tell you.

1. 1Photograph the house before the season starts. Every room, every system, the serial numbers on your equipment. Date stamped photos give you a record of the condition of the house before any water arrives.

1. 1Decide now who holds keys and who has your permission to enter after a storm. Roads close. Utilities get shut off. Access rules tighten. Someone already on your list moves faster than someone you are arranging by phone from a thousand miles away.

1. 1Get what you can off the floor. Anything stored in the garage, anything in a low cabinet, anything with a motor sitting on a slab.

1. 1Write down your licensed contractors now. After a landfall the good ones book fast. You do not want to be searching for one while standing in a wet house.

What a visit catches that a neighbor or a camera does not

A camera shows you a room until the power fails. Then it shows you nothing. A neighbor can tell you the street looks passable. Neither one walks the inside of your house, opens the closets, looks under the sinks, smells the air, or reads the ceilings for stains.

A visual property check does. Certified Coastal Home Watch walks your Nokomis home on a schedule and sends you time stamped photos of what we found. We do not make repairs and we cannot stop a storm. We check, we document, and we tell you. That is what turns a house you cannot see into a decision you can actually make.

Book a consultation at https://certifiedcoastalhomewatch.com and we will walk through your property and your schedule.
