A drought occurs when a long period of time passes without any substantial precipitation. Since different sections of the country receive widely differing amounts of rainfall, the amount of time it takes for drought conditions to develop differs throughout the country. The frequency is difficult to measure since droughts can occur at any time of the year.
The primary risk associated with a prolonged drought is an emergency water shortage. If this occurs, conserving water is extremely important. Pay attention to local news and follow the instructions of authorities during a drought to conserve water. The water you save may be enough to protect the critical needs of another person.
