Real-time coverage of floods event — Green Flood in Thailand from: 30 Jul 2026 01 to: 10 Aug 2026 01. — Pandita Data.
🌊 OPEN LIVE 3D WEATHER ALERTSA significant flood event is unfolding across northern Thailand's Lamphun Province from July 30 to August 10, 2026, triggered by the Southwest Monsoon system dumping extreme rainfall over the Ping River watershed. Communities in the Chiang Mai-Lamphun corridor face acute inundation risk, with river levels expected to exceed critical thresholds as upstream runoff converges in confined valley channels.
The Green Flood—named for its seasonal monsoon origin—threatens agricultural land, residential zones, and transportation infrastructure across a densely populated region home to over 400,000 residents. Historical data shows similar July–August monsoon floods in 2011 and 2020 displaced thousands and caused crop losses exceeding 500 million Thai baht.
The Southwest Monsoon delivers moisture-laden air masses across the Indian Ocean and Bay of Bengal, colliding with Thailand's western mountain ranges. This orographic lifting forces air to rise, cool, and release precipitation—up to 300–500mm over 5–7 days in the Ping River basin near coordinates 18.788°N, 98.986°E (Lamphun District). The Ping, a major tributary of the Chao Phraya River, has limited flood-storage capacity due to steep valley gradients and saturated soil conditions from antecedent rainfall.
Real-time NOAA satellite rainfall estimates and USGS stream-gauge data feed Pandita's weather and hydrology simulations, displaying radar-derived precipitation maps and river-level forecasts. Users can overlay historical monsoon patterns to assess return periods and flood extent probability across Lamphun Province.
Southwest Monsoon (May–September) is Thailand's primary flood season. July–August peak typically generates 5–8 significant riverine floods annually. Lamphun lies in the Ping River's confined valley—highest vulnerability zone. Urban and agricultural expansion has reduced wetland flood-storage capacity by 40% since 2000.
