When is a Heat Warning in effect?

• A. Between 0900 and 1500.
• B. Between 1300 and 1900.
• C. All day.
• D. Only during nighttime hours.

Answer: (B)

A Heat Warning is typically in effect during the hottest parts of the day when temperatures are likely to rise to levels that can pose health risks, especially for vulnerable populations. The correct answer indicates that the warning applies specifically between 1300 and 1900, which is the period of peak daytime heat in many regions. During these hours, maximum temperatures are most likely to be reached, and heat-related illnesses become more prevalent. This awareness is crucial for safety, as individuals are more exposed to heat stress during this time. The first choice suggests a time frame that starts too early in the day, while the third choice implies that the warning is effective all day, which would not allow for focused preventive measures during the high-risk hours. The last choice focuses on nighttime, which is generally cooler and does not typically require a heat warning.
