Dr. Paula Jo Colescott discusses avoiding bad weather while hiking. Hikers should check the daily weather forecast and be aware that hot temperatures and thunderstorms pose dangers. When hiking in hot conditions, hikers need to bring extra water to avoid dehydration. Thunderstorms present hazards such as falling trees and flooded paths, so hikers should learn how to spot signs of an approaching storm beyond just the daily forecast. Being vigilant about weather is especially important during thunderstorm seasons in different areas.
