What is the decoding for +SHRA?

The correct decoding for +SHRA is heavy rain showers. In aviation meteorology, the notation used to describe precipitation is standardized to provide clear and concise information about the intensity and type of precipitation present.

The "+" prefix indicates an intensity greater than that of normal rain showers, specifically denoting heavy rain. The "SHRA" portion stands for "showers of rain." When combined, +SHRA signifies heavy rain showers, alerting pilots and aviation personnel to the potential for significant weather impacts.

Understanding these notations is crucial for safe flight planning and navigation, as heavy rain can affect visibility and aircraft performance. While lighter rain showers are indicated by just "SHRA" without the "+" sign, the presence of the plus sign is a key detail that signifies the elevated intensity associated with heavy rainfall.
