Hurricanes are powerhouse weather events that suck heat from tropical waters to fuel their fury. These violent storms form over the ocean, often beginning as a tropical wave—a low pressure area that moves through the moisture-rich tropics, possibly enhancing shower and thunderstorm activity.
How does a hurricane start?
Whipping up a hurricane calls for a number of ingredients readily available in tropical areas:
A pre-existing weather disturbance: A hurricane often starts out as a tropical wave. Warm water: Water at least 26.5 degrees Celsius over a depth of 50 meters powers the storm. Thunderstorm activity: Thunderstorms turn ocean heat into hurricane fuel. Low wind shear: A large difference in wind speed and direction around or near the storm can weaken it.

What are the four stages of a hurricane?
A tropical disturbance is this formation of loosely packed rain clouds forming thunderstorms. A tropical disturbance requires specific criteria to take the next step to become a tropical depression.
There are six widely accepted conditions for hurricane development: 1. The first condition is that ocean waters must be above 26 degrees Celsius (79 degrees Fahrenheit). Below this threshold temperature, hurricanes will not form or will weaken rapidly once they move over water below this threshold.
For a hurricane to form certain weather conditions must be present. Hurricanes need both warm moist air and water. The water temperature needs to be 80 degrees or more and must be at least 150 feet deep for a hurricane to form. Hurricanes from over the Atlantic and Eastern Pacific Oceans near the equator.
Do Hurricanes need cold water to form?
The storm becomes a hurricane when there are sustained winds of over 73 miles per hour. When a hurricane travels over land or cold water, its energy source (warm water) is gone and the storm weakens, quickly dying.
How do Hurricanes get so big?
When it is on, Nazare is the biggest wave in the world.
Why do tropical cyclones dissipate or weaken? Do typhoons weaken after landfall? What will happen to a typhoon when it landfalls or hits landmasses? Why do tropical cyclones weaken after they hit land? How are landmasses and bodies of water effect typhoons? How does wind shear affect a tropical cyclone? Why do Hurricanes lose strength in the ocean?
Another thing we asked ourselves was: why are hurricanes so dangerous?
When hurricanes strike land they can cause huge amounts of damage. Most of the damage is caused by flooding and storm surge. Storm surge is when the ocean level rises at the coastline due to the power of the storm. Hurricanes also cause damage with high speed winds that can blow down trees and damage homes.
How should I prepare for a hurricane?
Prepare your hurricane supplies-refer to the list provided for guidance on supplies. Stay informed of the latest updates and evacuation orders. Prepare a detailed list of information about the specifics of your medication regime. Consult your physician and medical supply vendors to make sure you are adequately prepared for a hurricane.
This of course begs the query “What should I do after a hurricane?”
Stay tuned to local radio, television, or NOAA Weather Radio for the latest news. Stay alert for extra rainfall and following flooding even after the storm has ended. Keep away from loose or dangling power lines, and drive only if needed are a few more items to look into.
