Florida Emergency Preparedness: Complete Hurricane & Disaster Guide

Florida faces more hurricanes than any other U.S. state, but tropical storms are just one of the many threats Floridians must prepare for. From the Panhandle to the Keys, the Sunshine State experiences flooding, extreme heat, lightning strikes, sinkholes, and tornadoes. This comprehensive guide covers everything Florida residents need to know to protect their families, homes, and businesses from the state's unique disaster risks.

Hurricane Preparedness: Florida's Primary Threat

Atlantic hurricane season runs from June 1 through November 30, with peak activity in August and September. Florida's 1,350 miles of coastline makes it uniquely vulnerable—no point in the state is more than 60 miles from saltwater. Hurricanes bring multiple hazards: high winds, storm surge, flooding, and tornadoes embedded within the storm system.

Understanding Hurricane Categories

The Saffir-Simpson scale measures hurricane intensity by sustained wind speed:

• Category 1 (74-95 mph): Dangerous winds cause some damage to roofs, gutters, and siding. Large tree branches break, power outages possible for days.
• Category 2 (96-110 mph): Extremely dangerous winds cause extensive damage. Shallow-rooted trees uprooted, power outages lasting days to weeks.
• Category 3 (111-129 mph): Devastating damage occurs. Electricity and water unavailable for weeks. Major roof damage, many trees snapped.
• Category 4 (130-156 mph): Catastrophic damage. Severe roof and wall damage, most trees snapped or uprooted. Area uninhabitable for weeks to months.
• Category 5 (157+ mph): Catastrophic damage. High percentage of homes destroyed. Area uninhabitable for weeks to months.

Critical reminder: Category doesn't determine evacuation—your zone does. A slow-moving Category 1 can cause more flooding damage than a fast-moving Category 3. Storm surge, not wind, is the deadliest hurricane hazard.

Florida Evacuation Zones Explained

Florida uses lettered zones (A, B, C, D, E in some counties) based on storm surge vulnerability, not wind exposure. Zone A faces the highest surge risk and evacuates first. Your zone determines when to leave:

• Zone A: May evacuate for Category 1+ storms. Includes barrier islands, low-lying coastal areas
• Zone B: May evacuate for Category 2+ storms. Slightly higher elevation, still vulnerable
• Zone C: May evacuate for Category 3+ storms. Moderate surge risk areas
• Zone D/E: Major hurricanes only. Higher elevation but may still receive mandatory orders
• Mobile homes: Evacuate for ANY hurricane regardless of zone

The 7-Day Hurricane Supply Kit

Florida Division of Emergency Management recommends supplies for at least 7 days—longer than the typical 72-hour recommendation. After major hurricanes, power may be out for weeks and stores may remain closed.

Water: One gallon per person per day × 7 days. Florida's heat and humidity increase hydration needs. A family of four needs at least 28 gallons. Store extra for pets and medical needs.

Food: Non-perishable items requiring no cooking or refrigeration. Include:

• Canned goods (meat, fish, beans, vegetables, fruit)
• Peanut butter, crackers, granola bars
• Dried fruit, nuts, trail mix
• Manual can opener (essential!)

Power and lighting:

• Flashlights and extra batteries
• Battery-powered or hand-crank radio (NOAA Weather Radio)
• Portable phone chargers, fully charged
• Generator and fuel (store safely away from home)

Hurricane-Proofing Your Home

Start preparations before hurricane season, not when a storm is approaching. Last-minute supplies sell out quickly, and contractors become unavailable.

Window and Door Protection

Flying debris—not wind—causes most window damage. Protection options from most to least effective:

1. Impact-resistant windows and doors: Permanent protection, adds home value, may reduce insurance
2. Permanent hurricane shutters: Accordion, roll-down, or Bahama style. Quick to deploy
3. Removable panel shutters: Metal or polycarbonate panels stored until needed
4. Plywood: 5/8" minimum thickness, pre-cut and labeled. Requires pre-installed hardware

Myth busted: Tape does NOT protect windows. It creates larger, more dangerous glass shards and wastes valuable preparation time.

Roof Preparation

Most hurricane home damage starts with the roof. Preventive steps:

• Have roof inspected annually; replace missing or damaged shingles immediately
• Install hurricane straps connecting roof to walls (required in new construction since 2002)
• Trim dead branches and remove dead trees that could fall on roof
• Clear gutters and downspouts for proper drainage
• Consider secondary water barrier under shingles

Garage Door Protection

Garage doors are often a home's weakest point. A failed garage door allows wind inside, potentially lifting the roof from within. Options:

• Replace with hurricane-rated garage door
• Install horizontal bracing kit
• Add vertical center brace

Pool Preparation

Florida pools require specific hurricane prep:

• DO NOT drain the pool—water weight prevents the pool shell from "popping" out of the ground
• Lower water level 1-2 feet to accommodate rainfall
• Turn off electrical power to pool equipment at the breaker
• Remove all pool deck furniture and store securely (NOT in the pool)
• Super-chlorinate (shock) before the storm to prevent algae growth during power outage
• Do NOT cover the pool—covers can be destroyed and create dangerous debris

When a Hurricane is Coming

72+ Hours Out

• Fill prescriptions and obtain backup supply
• Fill car gas tanks (including spare vehicles)
• Withdraw cash (ATMs don't work without power)
• Charge all devices and backup batteries
• Review evacuation routes and identify shelter location

48 Hours Out

• Begin installing window protection
• Bring in or secure outdoor furniture, grills, decorations
• Fill bathtubs and extra containers with water for flushing toilets
• Review insurance documents; photograph home contents
• If evacuating, make reservations and plan route

24 Hours Out

• Complete all outdoor preparations
• Move vehicles to protected area
• Freeze extra water containers and fill freezer gaps with ice bags
• Set refrigerator and freezer to coldest settings
• If evacuating, leave early—roads become congested

Florida Flooding: Beyond Hurricanes

Florida's flat terrain, high water table, and abundant rainfall make it the most flood-prone state in the nation. Flooding occurs year-round, not just during hurricane season.

Types of Florida Flooding

Storm surge: Ocean water pushed ashore by hurricane winds. The deadliest hurricane hazard, storm surge can rise to 20+ feet in extreme cases. Surge moves fast—you cannot outrun it on foot.

Coastal flooding: King tides and tropical weather cause street flooding even without hurricanes. Common in Miami-Dade, Broward, and coastal communities statewide.

River flooding: Heavy rainfall upstream causes rivers to overflow banks. The St. Johns, Suwannee, and Apalachicola Rivers are particularly flood-prone.

Flash flooding: Sudden flooding from intense rainfall. Common during afternoon thunderstorms. Six inches of fast-moving water can knock you down; 12 inches can float most vehicles.

Urban flooding: Pavement prevents absorption, overwhelming drainage systems. Parking lots, underpasses, and low-lying streets flood quickly.

Flood Insurance: Essential for Florida

Standard homeowners insurance does NOT cover flooding. Key facts:

• 25% of flood claims come from outside high-risk zones
• NFIP policies have 30-day waiting period—buy before hurricane season
• Maximum coverage: $250,000 structure, $100,000 contents
• Private flood insurance may offer higher limits and faster claims
• Renters can (and should) purchase contents-only flood coverage

Extreme Heat: Florida's Year-Round Threat

Heat kills more Floridians annually than hurricanes. With heat indexes regularly exceeding 105°F in summer, heat-related illness is a serious concern—especially during power outages when air conditioning fails.

Recognizing Heat Illness

Heat cramps: Muscle cramps from dehydration and electrolyte loss. Stop activity, rest in cool place, drink water with electrolytes.

Heat exhaustion: Heavy sweating, weakness, cold/pale/clammy skin, nausea, dizziness. Move to cool area, apply cool cloths, sip water. Seek medical attention if symptoms worsen.

Heat stroke: Body temperature above 103°F, hot/red/dry skin, rapid pulse, confusion, unconsciousness. CALL 911 IMMEDIATELY. Move to cool area, try to lower body temperature with any means available. Do NOT give fluids.

Cooling Without AC

When power fails during Florida's brutal summer:

• Use battery-powered fans strategically
• Apply wet towels to neck, wrists, and ankles
• Stay on lowest floor (heat rises)
• Go to public cooling centers (libraries, community centers)
• Avoid using ovens or stoves, which add indoor heat
• Stay hydrated—drink before you feel thirsty
• Avoid alcohol and caffeine, which dehydrate

Protecting Vulnerable People

Check frequently on elderly neighbors, young children, those with chronic conditions, and outdoor workers. These groups are most vulnerable to heat illness. Never leave children or pets in vehicles—interior temperatures can reach 130°F in minutes, even with windows cracked.

Lightning: Florida is the Capital

Florida experiences more lightning strikes than any other state—about 1.4 million per year. Central Florida, particularly between Tampa and Orlando, is the "Lightning Alley" of the United States. Most strikes occur during afternoon summer thunderstorms.

Lightning Safety Rules

30-30 Rule: If the time between seeing lightning and hearing thunder is 30 seconds or less, go indoors. Stay inside for 30 minutes after the last thunder.

When caught outside:

• Get to a substantial building or hard-topped vehicle immediately
• Avoid open fields, hilltops, isolated trees, water, and metal objects
• Crouch low (don't lie flat) if you can't reach shelter, minimizing contact with ground
• Never shelter under tall isolated trees or in open structures like gazebos

Indoor safety:

• Avoid water—don't shower, bathe, or wash dishes
• Stay away from windows and doors
• Don't use corded phones or touch electrical equipment
• Surge protectors help but may not prevent all damage

Florida Sinkholes

Florida's limestone bedrock makes it prone to sinkholes—sudden ground collapse caused by dissolving rock beneath the surface. West-central Florida (Pasco, Hernando, Hillsborough counties) experiences the highest sinkhole activity.

Warning Signs

• Previously buried structures (fence posts, foundations) becoming exposed
• Trees or fence posts tilting or falling
• Doors and windows that don't open/close properly
• Cracks in foundation, walls, or pavement
• Circular depressions in yard
• Well water becoming cloudy or muddy
• Small ponds forming where none existed

What to Do

If you suspect sinkhole activity:

1. Do NOT enter the area—sinkholes can grow rapidly
2. Keep children and pets away
3. Contact a professional geologist or engineer
4. Report to your insurance company and county
5. Document with photos from a safe distance

Insurance note: Florida law requires insurers to offer sinkhole coverage, but it's often expensive. "Catastrophic ground cover collapse" coverage (included in standard policies) has a much higher damage threshold.

Tornadoes in Florida

Florida ranks third nationally in tornado frequency. While most are weak (EF0-EF1), they're often embedded in hurricane rain bands with little warning, or occur during fast-moving storm systems.

Tornado Safety

At home: Go to the lowest floor, interior room away from windows. Closets, bathrooms, and under staircases provide protection. Cover yourself with mattress or heavy blankets.

In mobile homes: LEAVE IMMEDIATELY. Mobile homes provide zero tornado protection. Go to a nearby sturdy building or lie flat in a ditch if no building is available.

In a vehicle: Do NOT try to outrun a tornado. Pull over, put car in park, keep seatbelt on, duck below window level. Cover your head. Do NOT shelter under overpasses.

Regional Considerations

South Florida (Miami-Dade, Broward, Palm Beach)

• Highest hurricane risk zone—direct hits common
• King tide flooding increasingly problematic
• Dense population complicates evacuation
• Multi-language emergency resources essential
• Condo dwellers: Know your building's hurricane plan

Central Florida (Orlando, Tampa Bay)

• Lightning capital—afternoon storms daily in summer
• Tampa Bay hasn't taken direct major hurricane since 1921—not immunity, just luck
• Sinkhole activity highest in region
• Theme park visitors may be stranded without transportation

North Florida (Jacksonville, Panhandle)

• Panhandle vulnerable to Gulf hurricanes—Hurricane Michael (2018) demonstrated catastrophic potential
• Jacksonville River (St. Johns) flooding during storm surge
• Occasional winter freezes require pipe protection
• More tornadoes than South Florida during severe weather outbreaks

Florida Keys

• Mandatory evacuation for all hurricanes—single road out
• Evacuate 48-72 hours early or you won't leave
• Overseas Highway closes at 45 mph winds
• Limited medical facilities—serious injuries require mainland transport
