One person died and another was injured in two separate incidents of electrocution.

A Chiang Rai woman also died while trying to save her drowning piglets and a novice monk was injured while wading in Tak.

Dee Mee Creek dyke was smashed last night after the heavy rain. The overflow water inundated 28 villages and swathes of farmland in Doi Luang sub-district. Residents in two tambons were evacuated to higher ground.

The storm, which receded to become a depression late on Sunday, brought heavy rains to the northern provinces of Chiang Mai and Tak and the southern provinces of Phuket, Songkhla and Satun. All were hit by flash-floods, mostly in suburban areas. Fishing trawlers operating off Phuket were warned about high seas as the island was hit by heavy rains.

Four schools in Tak province were ordered closed after flash-floods hit the municipal area. Officials and rescue workers were monitoring the water level as it went dangerously close to breaching safety levels - 50 centimetres for Ban Hua Fai reservoir and two metres for the Moei River.

Although Chiang Mai was not badly affected by Washi, residents of Omkoi district were warned about possible landslides.

Meanwhile, a storm in Satun damaged 30 houses and caused a power blackout in Manang sub-district, delaying the vote count following local elections on Sunday.

In Songkhla, 12 homes in Na Mom and Hat Yai districts and a radio tower in municipal areas were also damaged by a storm.

Interior official Sujarit Pajchimnant said provincial authorities had been instructed to prepare rescue operations and emergency relief efforts in case of flash-floods or other emergencies.
