Florida Storm Preparedness & Safety Planning

In Florida, the risk of severe tropical cyclones and hurricanes is notably high accounting for approximately 41 % of all U.S. hurricane landfalls since 1851.

Between 1980 and 2024 the state recorded 94 tropical-cyclone disaster events exceeding $1 billion in losses, part of 94 total billion-dollar weather/climate disasters in that period.

The 2025 Atlantic hurricane season is forecasted to be above‑average, with the National Oceanic and Atmospheric Administration (NOAA) expecting 13 to 19 named storms, 6 to 10 of which could become hurricanes, including 3 to 5 major hurricanes (Category 3 or higher).

By following this checklist, business owners, property managers and contractors in Sanford and the larger Central Florida region will have a strong defence against the next big weather event. It positions you beyond “just responding” and into being proactive, a key part of long-term commercial building storm preparedness.

Why Every Florida Business Needs a Disaster Recovery Plan

Florida’s commercial buildings face frequent hurricanes, tropical storms, and flash flooding. A well-designed storm preparedness checklist ensures your operations, staff, and physical assets remain protected. From safeguarding electrical systems to implementing disaster recovery plans, preparation is essential to reduce downtime and financial losses.

A reliable commercial generator is a key component of your plan. The right commercial-grade system will automatically restore power in seconds, keeping critical systems running, from server rooms to life-safety equipment.

Key Benefits of Proper Storm Preparedness:

  • Protects employees, customers, and visitors from harm
  • Prevents long-term damage to commercial buildings and assets
  • Minimizes operational downtime after severe weather
  • Supports compliance with local and state safety regulations
  • Enhances resilience for long-term commercial building storm preparedness

Planning ahead is more than just securing your property, it’s about business continuity. Businesses that integrate disaster recovery plans for businesses and backup power solutions are far more resilient when hurricanes strike.

The Saffir–Simpson Hurricane Wind Scale: Know What You’re Up Against

Before every storm, understanding hurricane strength helps you plan effectively. The Saffir–Simpson Hurricane Wind Scale measures potential property damage based on sustained wind speeds from Category 1 storms with minimal impact to Category 5 hurricanes capable of catastrophic destruction.

Category

Wind Speed 

(MPH)

Potential Damage

Category 1

74–95 mph

Minor damage to roofs, gutters, and power lines. Short-term outages possible.

Category 2

96–110 mph

Extremely dangerous winds cause extensive damage to roofing and trees. Several-day power outages are likely.

Category 3

111–129 mph

Devastating damage occurs; trees uprooted, roofs and small buildings destroyed; prolonged power outages.

Category 4

130–156 mph

Catastrophic damage; most trees uprooted, widespread blackouts for weeks.

Category 5

157+ mph

High percentage of homes destroyed; total failure of many buildings, widespread devastation; power outages lasting weeks to months.

 

*Even lower-category storms can disrupt utilities and communications that’s why having a standby generator isn’t optional in Florida; it’s essential. Power outages can last days or even weeks, making a whole-home generator a critical part of your storm preparedness plan.

Pro Tip: When a hurricane reaches Category 3 or higher, it’s time to activate your emergency plan and ensure your generator is fully fueled and functional.

  • First-aid kit with bandages, antiseptic, and prescription medications
  • Multi-tool and duct tape
  • Personal hygiene items and sanitation supplies
  • Fire extinguisher

Communication and Documents

  • Battery-powered or hand-crank weather radio
  • Important documents in waterproof bags (ID, insurance papers, medical info)
  • Emergency contact list (printed and digital)

For Pets

  • Food, water, and medications for at least one week
  • Pet carriers or crates
  • Copies of vaccination records

Pro Tip:

Use a portable generator or power bank to keep critical devices like phones, radios, and medical equipment charged when the grid goes down.

Have a Plan: Protect Your Family and Property

Before storm season peaks, make sure you and your family know exactly what to do. Preparation reduces panic and ensures everyone stays safe.

1. Know Your Evacuation Zone

Visit your county’s official emergency management website to determine your evacuation zone and routes in advance

2. Identify Safe Rooms or Shelters

If evacuation isn’t necessary, designate an interior, windowless room as your “safe zone.”

3. Create a Family Communication Plan

If evacuation isn’t necessary, designate an interior, windowless room as your “safe zone.”

4. Secure Your Property

Trim trees, anchor outdoor furniture, and protect windows with shutters or plywood. Keep your generator elevated and covered to prevent flood damage.

5. Schedule Generator Maintenance

Ensure your standby or whole-home generator is inspected and serviced before the first major storm arrives. Certified installers can test your transfer switch, check fuel lines, and confirm your generator is hurricane-ready.

If You Stay:

  • Choose a safe, interior room with no windows.
  • Keep your generator properly ventilated outdoors and away from windows or doors.
  • Have a disaster survival kit accessible.
  • Know your child’s school or daycare plan.
  • Identify neighbors who have medical training or generators.
  • Secure pets indoors with food and comfort supplies.

If You Evacuate:

  • Know your county evacuation routes and local shelters.
  • Designate a family contact person outside your area.
  • Keep fuel tanks full and generator transfer switches ready for use upon return.
  • Bring important documents, medications, and pet supplies.
  • Stay tuned to official hurricane updates from the National Weather Service or local authorities.

Planning for Long-Term Commercial Building Storm Preparedness

Storm preparedness isn’t just a one-time activity. Long-term planning includes:

  • Regular Maintenance & Inspections: Ensure roofs, windows, and HVAC systems are storm-ready year-round.
  • Continuous Staff Training: Update safety protocols for new employees and refresher sessions for existing staff.
  • Vendor & Contractor Agreements: Have backup contractors for generator maintenance, repairs, and flood mitigation.
  • Insurance Reviews: Confirm coverage for wind, flood, and business interruption.
  • Emergency Drills: Conduct semi-annual drills for evacuation and equipment shutdown procedures.


This proactive approach reduces risk exposure and keeps your business operational even in severe weather conditions.

Risks of Attempting a DIY Installation

Structural & Site Safety Measures

Commercial buildings in Florida must be structurally prepared for high winds, heavy rain, flooding and possible storm surge. This part of the checklist ensures your building site and nearby structures are reinforced and secured.

Key steps include:

  • Inspect the roof, windows, doors, facade and overhangs for wear, corrosion or loose components. Replace or reinforce as needed.
  • Clear gutters, drains and downspouts; ensure proper drainage away from the building to reduce flooding risk.
  • Secure or remove loose exterior items (signage, landscaping, outdoor equipment) that could become projectiles in high winds.
  • Ensure exterior generators (if any) are mounted to code, anchored properly and protected from flooding or wind damage.
  • Check access roads, parking lots and evacuation routes ensure they remain clear and free of debris.
  • Review your commercial building storm preparedness plan for flooding zones or hurricane prone areas. Consider the need for flood barriers or elevated equipment.


By proactively managing the structural integrity of the site, you reduce the risk of costly damage during a storm and simplify your recovery process. This gives you more confidence when you also contact a trusted commercial generator installer like GenStar.

Backup Power & Disaster Recovery Plans for Businesses

A robust generator and power strategy is a cornerstone of long-term commercial building storm preparedness, especially in Florida, where hurricanes and tropical storms frequently threaten. 

Generator & Power Strategy

  • Conduct a site-specific load calculation: determine what circuits and systems must stay online (for example: lighting, HVAC, servers, refrigeration, emergency lighting).
  • Evaluate backup power options: whole-building fixed standby generators (brands like Generac, Kohler, Briggs & Stratton, Tradewinds) vs portable units. GenStar specializes in certified commercial installations.
  • Pre-storm fuel supply: ensure diesel or natural gas supply is adequate; consider automatic refuel contracts or on-site storage if allowable.
  • Automatic transfer switch (ATS) testing: confirm that when utility power fails, the generator starts and transfers load without manual intervention.
  • Maintenance inspection: check oil levels, coolant, belts, battery, control panel, enclosure integrity, and simulate load test ahead of storm season.
  • Remote monitoring: implement remote alerts for generator faults, fuel status or power transfer events to ensure rapid response.
  • Document your electrical schematics, generator wiring diagrams, fuel connections and maintenance records so recovery teams can act fast after a storm.

Disaster Recovery Plans for Businesses

  • Develop a business continuity plan (BCP) that includes: key systems, backup locations, data recovery strategies, and minimum uptime targets.
  • Identify mission-critical equipment and set recovery time objectives (RTOs) and recovery point objectives (RPOs).
  • Ensure your insurance policy is reviewed for storm damage, business interruption, and backup power contingencies.
  • Conduct staff training and drills: simulate power loss, data loss, and communications failure to ensure everyone knows roles and responsibilities.
  • Prepare communication protocols: maintain an up-to-date contact list of staff, contractors, vendors, utility companies and recovery partners like GenStar.
  • Store critical data off-site or in the cloud, ensure backups are tested and recoverable.

After the storm, perform a damage assessment, execute your recovery plan and document everything for insurance and repair purposes.

By combining a licensed, commercial generator installation and maintenance framework with a comprehensive disaster recovery plan, your building in Sanford or Central Florida will be far more resilient to storms and power outages.

Communication, Staff & Operational Continuity

Storm readiness isn’t just about equipment, it’s about people, processes and communications. This section covers how to keep your team, tenants and stakeholders informed, and operations running before, during and after a storm.

Staff & Tenant Communications

  • Create an internal alert system (SMS, email, phone tree) to notify employees, contractors and tenants about impending storms, evacuation orders or power loss.
  • Assign a storm readiness coordinator or team (for property managers, facility managers, business owners) responsible for making decisions and overseeing preparations.
  • Provide clear instructions to staff and tenants on securing their own equipment, backing up data, and relocating critical operations if needed.
  • Establish a “call-home” or “check-in” procedure after the storm for all key personnel.

Operational Continuity

  • Maintain a prioritized list of business functions and systems that must remain operational or be restored first (for example: refrigeration, server rooms, customer service operations, point of sale).
  • Require off-site backups, cloud redundancy or alternate work sites for key personnel if the building is inaccessible.
  • Plan for temporary power or cooling solutions if the main generator or HVAC fails (rental units, modular chillers, satellite offices).
  • Test communications links: internet, phone, cellular, Wi-Fi ensure redundant paths where possible.
  • After the storm, coordinate with your generator partner for inspections and load-testing before fully restoring operations. GenStar offers 24/7 emergency generator service in Central Florida.


By establishing a clear operational continuity plan and communication chain, you reduce confusion, downtime and losses when a storm hits your commercial building.
