Relevant agencies in Nan have stepped up disaster prevention efforts as a new storm has arrived in the northern province.
Municipal and civil workers have teamed up to fix the flood wall which collapsed after a rapid surge in run-off earlier last week. A report says the storm is affecting 15 districts. Foothills and riverfront communities are susceptible to flash floods and mudslides.
The local disaster prevention agency has readied the drainage system and rescue supplies.
Residents in flood-prone areas have been warned to stay updated on the situation and stock up on necessary items that are enough for at least three days.
Rescue units are on standby round the clock to help in evacuation and life-saving tasks. Thunder showers will continue in the province until next week.
