A red flag warning is a weather-related alert issued by meteorological authorities, particularly in regions prone to wildfires.
It signifies that weather conditions are conducive to extreme fire danger. Factors that can lead to a red flag warning include low humidity, strong winds, high temperatures, and dry vegetation.
During a red flag warning, people are advised to exercise extreme caution to prevent accidental fires, and authorities often implement fire bans and restrictions. Firefighters and emergency services are usually on high alert during these warnings, as the risk of wildfires spreading quickly is significantly heightened.
