What does the abbreviation "BLPY" stand for in weather reporting?

In weather reporting, the abbreviation "BLPY" stands for "blowing spray." This term refers to the presence of small water droplets suspended in the air that are swept up by the wind, often occurring near large bodies of water such as oceans or lakes, usually due to wave action. Understanding weather abbreviations like "BLPY" is important for pilots and those involved in aviation, as these conditions can impact visibility and overall flight safety.

The other terms—blowing snow, blowing fog, and blowing rain—though they suggest similar phenomena, are represented by different abbreviations in meteorological reports. For example, blowing snow and blowing rain would have specific notations to indicate their presence, but "BLPY" specifically refers to the occurrence of blowing spray.
