PK WND stands for "Peak Wind" in the remarks section of a METAR report. Reports the highest instantaneous wind speed observed since the last routine observation, including the direction and the time it occurred. Encoded as PK WND followed by direction (three digits), speed (two or three digits in knots), and time (in hours and minutes after the hour). For example, PK WND 28045/15 means peak wind from 280 degrees at 45 knots at 15 minutes past the hour.
PK WND appears in the remarks (RMK) section at the end of a METAR observation. The remarks section follows the main body of the METAR and provides additional details about the observation that don't fit into the standard coded format.
Here is an example: "PK WND 28045/15". This appears in the remarks section and indicates peak wind information as part of the weather observation.
