There are plenty of jokes about the four seasons in Florida—in place of spring, summer, fall, and winter; we have tourist, mosquito, hurricane, and football seasons. The weather and change in seasons are definitely different in a mostly-subtropical state, although we in north Florida do get our share of cold weather (remember that snow this year?!).

All jokes aside, hurricane season is a real issue in our state. With the official season having recently begun (June 1) and running through November 30, hurricanes in the Gulf-Atlantic region are a legitimate concern for fully half the calendar year. According to records kept since the 1850’s, Florida has been hit with more than 120 hurricanes, double that of the closest high-frequency target, Texas. Hurricanes can affect areas more than 50 miles inland, meaning there is essentially no place to hide in our long, skinny, peninsular state.

I point all these things out not to cause anxiety, but to remind readers (and especially new Florida residents) that is it imperative to be prepared for hurricane season. Just like picking up pens, notebooks, and new clothes at the start of the school year, it’s important to prepare for hurricane season by firing up (or purchasing) a generator, creating a disaster kit, and making an evacuation plan. We even have disaster preparedness sales tax exempt holidays in Florida; one in early June and another in the heart of the season, August 24-September 6.
Peak season for hurricanes is September. Particularly for those in the far western Panhandle, September 16 seems to be our target—Hurricane Ivan hit us on that date in 2004, and Sally made landfall exactly 16 years later, in 2020. But if the season starts in June, why is September so intense? By late August, the Gulf and Atlantic waters have been absorbing summer temperatures for 3 months. The water is as warm as it will be all year–in 2023 even reaching over 100 degrees Fahrenheit–as ambient air temperatures hit their peak. This warm water is hurricane fuel—it is a source of heat energy that generates power for the storm. Tropical storms will form early and late in the season, but the highest frequency (and often the strongest ones) are mid-August through late September.
Pay attention to local meteorologists on social media, news, and radio. This alert was posted just yesterday online by the Escambia County Emergency Management Coordinator.
If you have lived in a hurricane-prone area, you know you don’t want to be on the front right side of the storm. For example, here in Pensacola, if a storm lands in western Mobile or Gulf Shores, Alabama, the impact will nail us. Meteorologists divide hurricanes up into quadrants around the center eye. Because hurricanes spin counterclockwise but move forward, the right front quadrant will take the biggest hit from the storm. A community 20 miles away but on the opposite side of a hurricane may experience little to no damage.

Hurricanes bring with them high winds, heavy rains, and storm surge. Of all those concerns, storm surge is the deadliest, accounting for about half the deaths associated with hurricanes in the past 50 years. Many waterfront residents are taken by surprise at the rapid increase in water level due to surge and wait until too late to evacuate. Storm surge is caused by the pressure of the incoming hurricane building up and pushing the surrounding water inland. Storm surge for Hurricane Katrina was 30 feet above normal sea level, causing devastating floods throughout coastal Louisiana and Mississippi. Due to the dangerous nature of storm surge, NOAA and the National Weather Service have begun announcing storm surge warnings along with hurricane and tornado warnings.
Coastal wetlands are some of the most ecologically productive environments on Earth. They support diverse plant and animal species, provide essential ecosystem services such as stormwater filtration, and act as buffers against storms. As Helene showed the Big Bend area, storm surge is devastating to these delicate ecosystems.
Hurricane Track on Wednesday evening.
As the force of rushing water erodes soil, uproots vegetation, and reshapes the landscape, critical habitats for wildlife, in and out of the water, is lost, sometimes, forever. Saltwater is forced into the freshwater wetlands. Many plants and aquatic animal species are not adapted to high salinity, and will die off. The ecosystem’s species composition can completely change in just a few short hours.
Prolonged storm surge can overwhelm even the very salt tolerant species. While wetlands are naturally adept at absorbing excess water, the salinity concentration change can lead to complete changes in soil chemistry, sediment build-up, and water oxygen levels. The biodiversity of plant and animal species will change in favor of marine species, versus freshwater species.
Coastal communities impacted by a hurricane change the view of the landscape for months, or even, years. Construction can replace many of the structures lost. Rebuilding wetlands can take hundreds of years. In the meantime, these developments remain even more vulnerable to the effects of the next storm. Apalachicola and Cedar Key are examples of the impacts of storm surge on coastal wetlands. Helene will do even more damage.
Many of the coastal cities in the Big Bend have been implementing mitigation strategies to reduce the damage. Extension agents throughout the area have utilized integrated approaches that combine natural and engineered solutions. Green Stormwater Infrastructure techniques and Living Shorelines are just two approaches being taken.
So, as we all wish them a speedy recovery, take some time to educate yourself on what could be done in all of our Panhandle coastal communities to protect our fragile wetland ecosystems. For more information go to:
Flooding due to heavy rains can cause septic systems to fail. Image: B. White NASA. Public Domain
About 30% of households in Florida rely on septic systems to treat and dispose of household wastewater. This includes all water from bathrooms and kitchens, and laundry machines.
Conventional septic systems are made up of a septic tank (a watertight container buried in the ground) and a drain field, or leach field. The septic tank’s job is to separate out solids (which settle on the bottom as sludge), from oils and grease, which float to the top and form a scum layer. Bacteria break down the solids (the organic matter) in the tank. The liquid wastewater or effluent, which is in the middle layer of the tank, flows out through pipes into the drain field and underlying soil, where most of the treatment takes placeDuring floods or heavy rains, the soil around the septic tank and in the drainfield become saturated, or water-logged, and the effluent from the septic tank can’t properly drain though the soil. Special care needs to be taken with your septic system during and after a flood or heavy rains.

What should you do after flooding occurs?
The U.S. Environmental Protection Agency (EPA) offers these guidelines:
If your water supply comes from a private well, have it tested for bacteria (total coliform bacteria and E. coli) to make sure it’s safe for consumption, which includes drinking, brushing teeth and cooking. Contact your local County Health Department for testing information. Use an alternate water source or boil your water (bring it to a rolling boil for at least 1 minute) before using it.
Relieve pressure on the septic system by using it less or not at all until floodwaters recede and the soil has drained. For your septic system to work properly, water needs to drain freely in the drainfield. Under flooded conditions, water can’t drain properly and can back up in your system. Remember that in most homes all water sent down the pipes goes into the septic system. Clean up floodwater in the house without dumping it into the sinks or toilet.
Avoid digging around the septic tank and drainfield while the soil is water logged. Don’t drive heavy vehicles or equipment over the drainfield. By using heavy equipment or working under water-logged conditions, you can compact the soil in your drainfield, and water won’t be able to drain properly.
Don’t open or pump out the septic tank if the soil is still saturated. Silt and mud can get into the tank if it is opened and can end up in the drainfield, reducing its drainage capability. Pumping under these conditions can cause a tank to pop out of the ground.
If you suspect your system has been damage, have the tank inspected and serviced by a professional. How can you tell if your system is damaged? Signs include: settling, wastewater backs up into household drains, the soil in the drain field remains soggy and never fully drains, a foul odor persists around the tank and drain field.
Keep rainwater drainage systems away from the septic drainfield. As a preventive measure, make sure that water from roof gutters doesn’t drain into your septic drainfield – this adds an additional source of water that the drainfield has to manage.

According to a recent article from Yale Climate Connections, Gulf waters are hotter this May than any year since oceanographers started measuring it in 1981.

Flooding after a storm can damage septic systems, causing them to fail. Image: B White, NASA Public Domain
After floods or heavy rains, the soil in your septic system drainfield can become waterlogged. But, for your septic system to treat wastewater, water needs to drain freely in the drainfield. Special care needs to be taken with your septic system after a storm in order to ensure its proper function.
What should you do if flooding occurs?
The U.S. Environmental Protection Agency (EPA) offers these guidelines:
Relieve pressure on the septic system by using it less or not at all until floodwaters recede and the soil has drained. Under flooded conditions, wastewater can’t drain in the drainfield and can back up in your septic system and household drains. Clean up floodwater in the house without dumping it into the sinks or toilet. This adds additional water that an already saturated drainfield won’t be able to process. Remember that in most homes all water sent down the pipes goes into the septic system.
If sewage from the septic tank has backed up into your house, clean up the affected area and disinfect the floor using a chlorine solution of a half cup of chlorine bleach to each gallon of water for thorough disinfection.
Avoid digging around the septic tank and drainfield while the soil is waterlogged. Don’t drive vehicles or equipment over the drainfield. Saturated soil is very susceptible to compaction. By working on your septic system while the soil is still wet, you can compact the soil in your drainfield, and water won’t be able to drain properly.This reduces the drainfield’s ability to treat wastewater and leads to system failure.
If you suspect your system has been damaged, have the tank inspected and serviced by a professional. How can you tell if your system is damaged? Signs include: settling, wastewater backs up into household drains, the soil in the drainfield remains soggy and never fully drains, a foul odor persists around the tank and drainfield. The tank shouldn’t be opened or pumped if the soil is waterlogged. Silt and mud can get into the tank if it is opened and can end up in the drainfield, reducing its drainage capability. Pumping under these conditions can cause a tank to float or ‘pop out’ of the ground and can damage inlet and outlet pipes. Only a licensed professional should clean or repair the septic tank.
For septic systems with electrical components, make sure to check all the electrical connections for damage before restoring electricity (to pumps, for example).
Have your private well water tested if your septic system or private well were flooded or damaged in any way. Your well water may not be safe to drink or to use for household purposes (making ice, cooking, brushing teeth or bathing). You need to have it tested for total coliform bacteria and E. coli to ensure it is safe to use.
Many county health departments provide testing for bacterial contamination. If they do not offer testing, they can help point you to commercial labs in the area for testing.
The Florida Department of Environmental Protection (FDEP) also maintains a site where you can search for certified water testing labs by county: Certified Water Testing Laboratories
