Easy Hurricane Basics in Under 5 Minutes

June 17, 2026 · The Clime Team

Hurricanes are powerful tropical storms that can cause significant damage through high winds, heavy rainfall, and flooding. Understanding their formation, potential impacts, and safety measures is crucial for residents in hurricane-prone areas.

What Are Hurricanes?

Hurricanes are large, organized systems of clouds and thunderstorms featuring a clearly defined circulation pattern. They form over warm ocean waters, typically between 5° and 20° latitude in both hemispheres. The Atlantic hurricane season runs from June 1 to November 30, while the Pacific season starts on May 15 and ends on November 30. (cdc.gov)

How Do Hurricanes Form?

Hurricanes develop from disturbances in the atmosphere over warm ocean waters. As warm, moist air rises, it creates a low-pressure system. If conditions are favorable, this system can intensify into a tropical storm and eventually a hurricane. The storm's rotation is driven by the Earth's Coriolis effect, leading to the characteristic cyclonic motion. (nationalgeographic.com)

What Are the Main Hazards of Hurricanes?

Hurricanes pose several significant threats:

Storm Surge: An abnormal rise in water level caused by the storm's winds, leading to coastal flooding.
Inland Flooding: Heavy rainfall can result in widespread flooding, affecting areas far from the coast.
High Winds: Sustained winds can cause structural damage, uproot trees, and create flying debris.
Tornadoes: Hurricanes can spawn tornadoes, adding to the destruction. (weather.gov)

How Are Hurricanes Classified?

Hurricanes are categorized based on their sustained wind speeds using the Saffir-Simpson Hurricane Wind Scale:

Category 1: 74-95 mph (119-153 km/h)
Category 2: 96-110 mph (154-177 km/h)
Category 3: 111-129 mph (178-208 km/h)
Category 4: 130-156 mph (209-251 km/h)
Category 5: 157 mph or higher (252 km/h or higher) (nsc.org)

What Should You Do Before a Hurricane?

Preparation is key to safety:

Create an Emergency Plan: Establish evacuation routes and designate a safe meeting place.
Assemble an Emergency Kit: Include essentials like water, non-perishable food, medications, flashlights, batteries, and important documents.
Secure Your Home: Install storm shutters or board up windows, and secure outdoor items that could become projectiles. (cdc.gov)

What Should You Do During a Hurricane?

If a hurricane is imminent:

Stay Indoors: Remain in a sturdy building, away from windows and doors.
Avoid Flooded Areas: Do not drive through flooded roads; just six inches of moving water can sweep away a vehicle. (weather.gov)
Listen to Authorities: Follow evacuation orders and stay informed through official channels.

What Should You Do After a Hurricane?

Post-storm safety includes:

Stay Alert: Be cautious of hazards like downed power lines and structural damage.
Avoid Floodwater: Floodwater can contain contaminants; avoid wading through it. (cdc.gov)
Check for Updates: Continue to monitor local news and official sources for recovery information.
