Resolution criteria

This market resolves to YES if measurable precipitation (at least 0.01 inches) is recorded in San Juan, Puerto Rico, during the upcoming Monday (12:00 AM to 11:59 PM local time, AST). Otherwise, this market resolves to NO.

Resolution will be determined by the official daily climate report or observation data for San Juan from the National Weather Service (NWS) Weather Forecast Office San Juan:

• Primary Source: NWS San Juan Climate Data (select station: Luis Muñoz Marín International Airport / TJSJ).

• Secondary Source: The 24-hour observation summary for TJSJ at aviationweather.gov.

A "trace" amount (T, less than 0.01 inches) does not qualify as measurable precipitation and will resolve as NO. If the creator intended a specific Monday date other than the upcoming one, the market description should be updated with the exact date.

Background

In meteorology and National Weather Service verification, a "rain day" typically requires at least 0.01 inches (0.25 mm) of liquid water accumulation. San Juan features a tropical climate with frequent brief showers; precipitation probabilities issued by the NWS represent the likelihood of at least 0.01 inches falling at any given point in the forecast area.
