How is a waterspout east of the observation location encoded for transmission in an observation?

In aviation weather reporting, the encoding of various phenomena is standardized to ensure clarity and consistency in communication. A waterspout is a significant weather phenomenon that may affect aviation operations. When a waterspout occurs east of the observation location, it is encoded with the direction indicated by the letter that represents where it is located in relation to the observer.

In meteorological reporting, cardinal directions are commonly used, with "E" representing east. Therefore, when the observation reports a waterspout to the east, it is essential to use the correct directional indicator to accurately inform pilots and other aviation professionals about potential hazards.

By using the term "WATERSPOUT E," the communication conveys precisely that the waterspout is located east of the reporting station, allowing for optimal situational awareness and the necessary adjustments to flight operations. This encoding is crucial for safe navigation and flight planning.
