FAA Ground School Practice Test

In the TAF for KMEM, what does "SHRA" indicate?

1. Heavy rain

2. Thunderstorms with rain

3. Rain showers

4. Snow showers

The correct answer is: Rain showers

The term "SHRA" in the TAF (Terminal Aerodrome Forecast) specifically refers to "showers of rain." This indicates that rain is expected to occur in a showery pattern, meaning the rain will come and go, rather than a steady downpour. In aviation weather reports, the designation is crucial as it helps pilots and flight planners assess weather conditions that may affect flight operations. Showers can have varying intensity and duration, but the term itself suggests intermittent precipitation rather than continuous rain, as might be indicated by a wording like "rain" without the "showers" prefix. Understanding this terminology assists pilots in preparing for variable weather conditions that can impact visibility and aircraft performance during takeoff, landing, and in-flight.
