A BMA official, who asked not to be named, said BMA Governor Assawin Kwanmuang will chair a ceremony to launch the app next week.

The app will be available for both Android and iOS devices, according to the source.

The app will be linked to the BMA’s flood prevention centre to provide comprehensive information about areas that have been hit with heavy rains, areas under flash flooding and areas where water-draining pumps will be installed.

The source said the app has been developed from the BMA Traffic app so the app will also report the traffic situations on Bangkok streets to users.

All in all, the app will advise motorists to avoid flooded roads or congested roads, the source added.

Moreover, Bangkok residents can use the app to file complaints about city woes, such as floods, traffic snarls, and garbage woes.

Users of the app can take photos from within the app and upload them to the BMA right away. The app will record GPS location of the photos and alert BMA agencies concerned to tackle the issues within 24 hours.

The source said the BMA earlier planned to release the app last month but it was postponed because the development could not be completed in time.
