Here's a breakdown:
* Average forward speed: Most hurricanes move at 10-20 mph.
* Slow-moving hurricanes: Some hurricanes can move very slowly, at less than 10 mph, which can lead to more intense and prolonged rainfall and flooding.
* Fast-moving hurricanes: Hurricanes can also move quickly, at over 50 mph, which can reduce the time for preparation and increase the risk of damage from wind and storm surge.
Factors affecting hurricane speed:
* Steering currents: The upper-level winds steer hurricanes.
* Pressure gradients: The difference in air pressure between the hurricane and its surroundings.
* Coriolis effect: The Earth's rotation deflects hurricanes.
* Terrain: Land masses can slow down hurricanes.
It's important to remember that hurricane speed is just one factor in determining the potential impact of a hurricane. The intensity, size, and track of the storm are also critical factors.
