The GOES-16 satellite's view of Hurricane Irma as a Category 5 storm on September 5, 2017.
This year's hurricane season is shaping up to be unusually active. The fourth hurricane of 2017, Irma, is now a Category 5 storm, and is heading towards the US Virgin Islands, Puerto Rico, and the Dominican Republic.
Although it's not yet known whether Irma will make landfall in the continental US, officials in the Florida Keys are already issuing evacuation recommendations and closing schools. The storm comes on the heels of Hurricane Harvey, which devastated parts of Texas, including Houston.
Several forecasting groups — including the Weather Company, which is behind the Weather Channel and Weather Underground — predicted a busier-than-normal hurricane season for 2017. Irma is already the fourth hurricane of 2017.
The peak of the season is around September 10, which means more hurricanes are likely. On Tuesday, a tropical storm named Jose formed in the Atlantic east of Irma, though it's too early to say where it will go.
The prevalence and severity of storms so far this year caught many people by surprise, however, and has left many others scrambling to prepare. If you're wondering what to do in the face of hurricane threats, the Federal Emergency Management Agency (FEMA) and the Department of Homeland Security (DHS) have resources to help people get ready. Here are some of their recommendations.

The most essential items on this list — whatever can be carried — should be packed in advance in a go-bag that can be grabbed quickly if an evacuation becomes necessary. Since grocery stores empty out and prices get gouged in an emergency situation, stocking up ahead of time is best.

FEMA and the DHS say it's essential to come up with an emergency plan for your family long before a disaster arrives. This plan should include packing your emergency supply kit and go-bag. It should also cover what you'll do in the event of a mandatory evacuation — which routes are safest in hurricanes, where all members of a household should try to go, etc.
In an ideal scenario, families should practice these plans ahead of time to work out any kinks and gain comfort with them before encountering stressful conditions.
To keep track of a developing storm, you can also sign up for alerts from the National Weather Service (NWS) and National Oceanic and Atmospheric Administration (NOAA).
Evacuate only if it's recommended or mandatory.
The most common reason for mandatory evacuation orders is a storm surge warning — that's the crest of water that forms from a storm's powerful winds. If you live in an area that could face such a threat, make an evacuation plan with your family that includes which roads you'll take and where you'll go. Generally, emergency shelters are set up in the days ahead of a storm, so you can consult FEMA or your local city government to determine where those will be.
However, some cities have good reason to avoid issuing evacuation orders. When Harvey hit Houston, officials didn't tell residents to leave in order to avoid clogging highways and other roads. Those drivers could have found themselves getting into accidents or stuck in bumper-to-bumper traffic as waters overtook roadways. When Hurricane Rita barreled toward Texas in 2005, an exodus of about 3 million people contributed to at least 73 deaths before the storm arrived.
So if there's no voluntary or mandatory evacuation in place for your area, stay put and keep your car in good working condition with a full gas tank in case a late evacuation order does come. Once a mandatory evacuation is put in place, however, you should leave immediately. That's why it's important to have a go-bag prepared.
It's common for power to go out during a major storm — an estimated 300,000 people were without it after Hurricane Harvey hit.
Because lighting candles can create a fire risk, flashlights with extra batteries are key. The DHS also recommends that you keep your cell phone fully charged as long as you have electricity.
If you're anticipating that power might go out, it's also a good idea to turn your freezer and refrigerator to their coldest settings about 6 hours before a storm hits. That way, food will last longer if the power goes out. You can also move things to the freezer if you won't need them right away.
If your house loses power, avoid opening the fridge and freezer doors as much as possible to keep cold air in. Watch the thermometer on those appliances — once perishable foods like meat, poultry, and milk have been stored above 40 degrees Fahrenheit for more than two hours, they should be thrown out. Freezing ice packs and preparing coolers to store food can help keep things fresh for longer.
It is possible, of course, to buy a portable generator or get one installed if you're planning far ahead. But any generator should be protected from moisture and kept outside, well away from any windows or doors.
Because there is also a chance water will be cut off after power has gone out, FEMA recommends filing sinks and bathtubs in order to have extra water to use for flushing toilets or washing.
Ready your house for flooding.
If heavy rainfall and flooding is a risk where you live, there are both cheap and expensive ways to prepare.
The simplest is to secure rain gutters to the house and clear clogged areas or drains to prevent water from building up and causing damage. You can also stockpile sand bags, plastic sheeting, and plywood to be used as necessary.
More costly preparations include installing sump pumps with backup batteries and a water alarm to alert you when the system is getting overloaded. It's also a good idea to waterproof your basement if you live in a flood-prone area, and to elevate your heating system, water heater, and electric panel to heights at which flood waters won't cause damage.
The most important (though often most difficult) precaution to take is avoiding walking or driving through flood waters. Even 6 inches of fast-moving water can knock a person down, and 12 inches can sweep away a car. The water can also hide dangerous debris and make it hard to tell where the ground has washed away. Plus, there's a risk of electricity from downed power lines, contamination from sewage and other chemicals, and wildlife like snakes and fire ants trying to escape.
Stay away from windows if there's heavy wind.
When heavy winds arrive, stay away from windows, since fast-moving debris could break the glass and fly into the house. FEMA recommends seeking shelter on the home's lowest level, in an interior room, though a flood risk could change that calculation.
If you're bracing for extreme winds, you should also reinforce doors, windows, walls, and roofs as much as possible in advance. Putting tape on windows does not help, however, since it could cause the glass to break into larger, deadlier shards. The DHS recommends bringing any outdoor objects (like patio tables and chairs) inside, and anchoring anything that shouldn't be indoors (like propane tanks).
If you have more time to prepare your house, the DHS recommends trimming and removing damaged trees and limbs to minimize the risk of them falling and causing damage or injuries. It may also be a worthwhile long-term investment to retrofit and secure your roof, windows, and doors, or to add storm shutters.
Remain cautious after a storm passes.

Even after a hurricane has passed, many dangers still lurk. FEMA suggests waiting for officials to say an area is safe before returning. The agency also recommends avoiding the use of electrical equipment, waiting for a given building to be inspected before entering it, and drinking bottled or boiled water until tap water is declared safe.
All food that was exposed to flood water (even if it's in a can or bottle) should be thrown out, as should anything perishable that was not kept at the proper temperature.
As far as insurance is concerned, it's best to take as many photos as possible of the initial damage, and to do what you can to prevent further damage (covering ceiling holes with tarps, for example) since insurance plans might not cover the losses sustained after a storm.
