Severe weather hazards are dangerous weather phenomena that threaten life and property. Within this topic, we discuss tornadoes, lightning, hail, flash flooding, and downbursts.

1.9b  Life Cycle of a Thunderstorm

A basic thunderstorm (single cell) goes through three phases during its lifetime: cumulus, mature, and dissipating. This can last between 30 minutes to an hour.

1.9c  Thunderstorm Classification

Although thunderstorms can vary in size and shape, we can classify them into four main groups: single cell, multi-cell clusters, multi-cell lines, and supercells.
