El Nino Watch
Numbered warning bulletins from the Thai Meteorological Department about heavy rain, strong wind-waves and storms. They are the official source for Thailand.
Hazards
The TMD issues numbered bulletins (for example "No. 12") when heavy rain, strong wind-waves or a storm threaten parts of Thailand. Each has an issue time and an end date, and often names the provinces and whether small boats should stay ashore.
The app reads them and checks which ones concern the Gulf side of the South / Surat Thani. They feed the flood, sea state and cyclone factors and the departure windows.
Official orders come from Thai authorities, not from this app. TMD hotline: 1182.
