This market will resolve to "Yes" if the listed city records measurable precipitation on August 9. Otherwise, this market will resolve to "No". Measurable precipitation means 0.01 inches or more as reported by the Weather Underground station page for the city. A report of trace ("T") does not qualify. Resolution is based on the station's first published precipitation figure for the day. Subsequent revisions or corrections to the published data will not be considered; the first published value is final. If no figure has been published by 11:59 PM ET on the day following the observation date, this market will resolve to "No".Trader sentiment for precipitation on August 9, 2026, across listed cities hinges on short-range model guidance and monsoon dynamics. The Intertropical Convergence Zone and regional monsoon flows drive convective activity over Southeast Asia and parts of South Asia, while subtropical highs and frontal boundaries influence patterns near Tokyo, São Paulo, and Sydney. National meteorological agencies issue updated quantitative precipitation forecasts and nowcasts that resolve measurable rain thresholds at official gauges; model spread in timing and location of showers creates uncertainty, especially for isolated convection. Historical August baselines show typical daily rainfall probabilities varying by latitude and elevation, with traders monitoring 48-hour forecast updates from sources such as the Japan Meteorological Agency, India Meteorological Department, and Bureau of Meteorology for resolution-relevant shifts.
