Understanding Hurricanes
Before delving into the specific history of hurricanes in St. Augustine, it's essential to understand what hurricanes are and how they form.
What is a Hurricane?
A hurricane is a type of tropical cyclone, a large storm system characterized by strong winds, heavy rain, and a defined circulation pattern. These storms typically develop over warm ocean waters and can cause widespread damage upon making landfall.
Key features of hurricanes include:
- Wind Speeds: Categorized on a scale from 1 to 5, with Category 1 being the least damaging and Category 5 the most destructive.
- Eye and Eyewall: The eye is the calm center of the storm, while the eyewall contains the most intense winds and rainfall.
- Storm Surge: The rise in seawater level caused by a hurricane's winds, which can lead to coastal flooding.
Hurricane Formation
Hurricanes generally form under specific conditions:
1. Warm Ocean Water: Typically, sea surface temperatures must be at least 80°F (27°C).
2. Atmospheric Instability: A warm, moist atmosphere encourages convection.
3. Low Wind Shear: Minimal changes in wind speed and direction at different altitudes promote the development of a storm system.
