How to Prepare for a Hurricane
By Brooke Bauman
As the climate changes and ocean temperatures and sea levels rise, flooding from hurricanes has become more serious. That's why it's important for people who live in places vulnerable to hurricanes to prepare for the dangers associated with flooding and storm surge.
How Climate Change is Influencing Storm Surge
Many people associate hurricanes with high winds, but storm surge — the wall of water pushed ashore by the storm — can be an equal or even greater danger for people and property.
"We want people to know that they can hide from the wind, but they need to run from the water," said Jay Wiggins, who directs the Emergency Management-Homeland Security Agency in Glynn County, Georgia.
Water weighs about 1,700 pounds per cubic yard. As it's pushed by hurricane winds, it can act like a battering ram, pummeling the shore and buildings.
Sea levels are rising in substantial part from warming ocean waters, melting glaciers, and ice sheets. Because of that sea-level rise, storm surges can inundate more coastline than they did in the past. Storm surges are particularly dangerous when they occur during high tide, because they can raise water levels by as much as 20 feet.
Although the overall number of hurricanes isn't known to be increasing, there is evidence that climate change is making some storms worse. For example, several studies have found that climate change increased the odds of the intense precipitation that fell during Hurricane Harvey, which made landfall in Texas in 2017. A 2013 study projected a 45-87 percent increase in the frequency of Category 4 and 5 hurricanes — the most dangerous categories — in the Atlantic Basin during this century.
How to Prepare for a Hurricane
Before a hurricane even pops up on the forecast, there are a few steps that you can take to prepare. Consider investing in flood insurance — or if you've already purchased it, familiarize yourself with the policy. Sign up for your community's emergency alert system.
If a hurricane is imminent, it's important to take additional precautions to minimize potential damage and threats to your safety. Here are some key steps that the Federal Emergency Management Agency recommends:
- Familiarize yourself with evacuation routes and plan to follow local evacuation orders if possible.
- If you are not ordered or are unable to evacuate, store enough food, water, supplies, and medications for at least three days.
- Put important documents in a safe, waterproof place.
- Charge all electronic devices that you might need.
- Turn your fridge to the coldest setting so that if you lose power, it will stay cooler for longer.
- Cover windows with plywood boards and place sandbags around doorways to reduce the risk of water damage — note that some flood insurance policies may cover up to $1,000 in avoidance measures to protect your property.
- Bring lightweight objects indoors.
- Create a plan to contact family and friends. Save phone calls for emergencies because the lines will likely be busy; rely mostly on text and social media to communicate.
What to Do During a Hurricane
FEMA warns to not walk, swim, or drive through floodwaters. Floods can develop quickly, so stay alert for the potential of flash flooding.
According to the Department of Homeland Security's Ready campaign, six inches of water can knock a person down and one foot of water can be enough to pick up some vehicles.
Avoid flood water. It may contain dangerous debris and be contaminated. Floodwaters also pose the danger of electrocution if electronics or downed power lines are exposed to water.
And creatures like snakes may lurk on or beneath the surface.
What to Do After a Hurricane
Before you begin to clean up, listen to authorities for further instructions. In addition, follow these FEMA guidelines.
- Stay off the roads unless it's an emergency.
- Avoid driving in or making contact with floodwaters.
- Beware of electrocution. Don't touch electrical equipment if it's wet or while you're standing in water.
- Use a generator or other gasoline-powered machinery only outdoors and away from windows.
- Always use heavy gloves and boots while cleaning to protect yourself from sharp objects and biting creatures.
- If your home was exposed to water, it likely contains mold. Consult these EPA guidelines on protecting your safety while cleaning mold after a flood.

The COVID-19 pandemic in the United States is the deepest and longest period of malaise in a dozen years. Our colleagues at the University of Vermont have concluded this by analyzing posts on Twitter. The Vermont Complex Systems Center studies 50 million tweets a day, scoring the "happiness" of people's words to monitor the national mood. That mood today is at its lowest point since 2008 when they started this project.
The Hedonometer measures happiness through analysis of key words on Twitter, which is now used by one in five Americans. This chart covers 18 months from early 2019 to July 2020, showing major dips in 2020. hedonometer.org<p>These same tweets also indicate a potential salve. Before pandemic lockdowns began, doctoral student <a href="https://scholar.google.com/citations?user=0P0ZYbIAAAAJ&hl=en" target="_blank">Aaron Schwartz</a> <a href="https://doi.org/10.1002/pan3.10045" target="_blank">compared tweets before, during, and after visits to 150 parks, playgrounds and plazas</a> in San Francisco. He found that park visits corresponded with a spike in happiness, followed by an afterglow lasting up to four hours.</p><p>Tweets from parks contained fewer negative words such as "no," "not" and "can't," and fewer first-person pronouns like "I" and "me." It seems that nature makes people more positive and less self-obsessed.</p><p>Parks keep people happy in times of global crisis, economic shutdown and public anger. Research has also shown that transmission rates for COVID-19 are <a href="https://www.sfchronicle.com/news/article/Is-risk-of-coronavirus-transmission-lower-15287602.php" target="_blank">much lower outdoors than inside</a>. As scholars who study <a href="https://scholar.google.com/citations?user=yFzb2EUAAAAJ&hl=en" target="_blank">conservation</a> and how nature <a href="https://scholar.google.com/citations?user=CCnUeN8AAAAJ&hl=en" target="_blank">contributes to human well-being</a>, we see opening up parks and creating new ones as a straightforward remedy for Americans' current blues.</p>
Park Visits Are Up During the Pandemic<p>According to the Hedonometer, sentiments expressed online started trending lower in mid-March as the impacts of the pandemic became clear. As lockdowns continued, they registered the lowest sentiment scores on record. Then in late May, effects from George Floyd's death in police custody and the following protests and police response once again could be seen on Twitter. May 31, 2020 was the saddest day of the project.</p><p>Recent surveys of park visitors around the University of Vermont have shown people <a href="https://osf.io/preprints/socarxiv/sd3h6" target="_blank">using green spaces more</a> since COVID-19 lockdowns began. Many people reported that parks were highly important to their well-being during the pandemic.</p>

Their impact on happiness is real, measurable and lasting.</p><p>Twitter records show that parks increase happiness to a level similar to the bounce at Christmas, which typically is the happiest day of the year. Schwartz has since expanded his <a href="https://arxiv.org/pdf/2006.10658.pdf" target="_blank">Twitter study</a> to the 25 largest cities in the U.S. and found this bounce everywhere.</p><p>Parks and public spaces won't cure COVID-19 or stop police brutality, but they are far more than playgrounds. There is growing evidence that parks contribute to mental and physical health in a range of communities.</p><p>In a 2015 study, for example, Stanford researchers sent people out for one of two walks: through a local park or on a busy street. Those who walked in nature showed <a href="https://doi.org/10.1016/j.landurbplan.2015.02.005" target="_blank">improved moods and better memory performance</a> compared to the urban group. And a team led by <a href="https://penniur.upenn.edu/people/eugenia-gina-south" target="_blank">Gina South</a> of the University of Pennsylvania showed in a 2018 study that greening and cleaning up blighted vacant lots in Philadelphia <a href="http://dx.doi.org/10.1001/jamanetworkopen.2018.0298" target="_blank">reduced local residents' feelings of depression, worthlessness and poor mental health</a>.</p>
Creative Strategies<p>It isn't easy to create new parks on the scale of San Francisco's Golden Gate Park or the Washington Mall, but smaller projects can expand outdoor space. Options include greening vacant lots, closing streets and investing in existing parks to make them safer, greener and shadier and support wildlife.</p><p>These initiatives don't have to be capital-intensive. In the University of Pennsylvania study, for example, renovating a vacant lot by removing trash, planting grass and trees and installing a low fence cost only about US$1,600.</p><p>Urban green space is most needed in neighborhoods that have lacked funding for parks, especially given <a href="https://www.nytimes.com/2020/04/08/nyregion/coronavirus-race-deaths.html" target="_blank">COVID-19's disproportionate impact on Black and Latinx people</a>.</p><p>Cities can also create parklike spaces by <a href="https://theconversation.com/with-fewer-cars-on-us-streets-now-is-the-time-to-reinvent-roadways-and-how-we-use-them-140408" target="_blank">closing streets to cars</a>. Many cities worldwide are currently retooling their transportation systems for the post-COVID-19 world in order to <a href="https://thecityfix.com/blog/bicycles-slower-speeds-livable-city-paris-mayor-anne-hidalgo-plans-ambitious-second-term-dario-hidalgo/" target="_blank">reallocate public space</a>, widen sidewalks and make more space for nature.</p><p>Urban designers, artists, ecologists and other citizens can play a direct role, too, creating pop-up parks and green spaces. Some advocates <a href="https://www.bloomberg.com/news/articles/2017-09-15/a-brief-history-of-park-ing-day" target="_blank">transform parking spaces into mini-parks</a> with grass, potted trees and seating for just the time on the meter, to make a larger point about turning so much public space over to cars.</p><p>Or cities can invest a little more. Minneapolis, Cincinnati and Arlington, Virginia, have won <a href="https://www.tpl.org/parkscore" target="_blank">national recognition</a> for their ambitious investments in public park systems. These areas could serve as models for neighborhoods that lack access to parks.</p>

A New Park Deal?<p>The United States has historically driven economic recovery with major infrastructure investments, like the New Deal in the 1930s and the 2009 <a href="https://www.investopedia.com/terms/a/american-recovery-and-reinvestment-act.asp" target="_blank">American Reinvestment and Recovery Act</a>.
