Mountain run-off hit almost 20 villages in the northern province of Lampang, while river overflow has worsened flooding in Nakhon Ratchasima, Chachoengsao, and Chon Buri, authorities say.
More than 100 households in 18 villages of Muang Pan district were hit by the run-off, which was caused by downpours in Jaeson National Park, assistant district chief Prapas Kamuanglue said yesterday.
The water gushed down from several mountains to the villages, he said, adding that about 1,000 rai of agricultural land was also flooded. Several roads were cut off. Police and soldiers have been sent to the area to offer help with disaster relief and rescue operations.
Meanwhile, in Chachoengsao, a huge mass of water overflowing from Seeyad reservoir in Tha Takiab district yesterday reached tambon Koh Khanoon in Phanom Sarakham district, flooding a 10km section of Highway No.3245, which was left under 60cm of water.
The water was expected to arrive in Ratchasan and Bang Khla districts last night and would worsen the situation in both areas, which are already inundated, officials said.
In Chon Buri, about 80 factories in Amata Nakhon industrial estate have been flooded but are still operating.
Wiboon Kromdis, an executive of Amata Corp PCL, said the industrial estate had built flood barriers and installed more than 50 pumps to drain water from the estate. The situation is expected to ease in a couple of days, he said.
In Nakhon Ratchasima, most of the floodwater on inbound lanes to the capital, between the 107-108 kilometre markers of Mittraphap Highway in Sung Noen district, has receded and the road ruled passable for vehicles.
The water level on the highway had fallen from 60-70cm on Sunday to about 15cm, police said.
Police opened one lane on the opposite side of the road, blocking its use by outbound vehicles, to allow travel towards Bangkok, but traffic backed up for about 1km.
In Phimai district, water gushing from the swollen Mun River has inundated Phimai National Museum and Park, where artefacts dating back over 1,000 years are kept. Museum staff wrapped the artefacts in plastic bags to protect them as water levels rose to 40cm.
Despite efforts to ease the flooding in the province, local dams are filling up, posing the threat of further flooding, officials said.
