There are now 72 evacuation centres in various provinces including Chiang Mai, Kanchanaburi and Phetchaburi.
To date, they have already sheltered 2,076 flood-hit residents of Bangkok and its adjacent provinces.
A major flood is threatening to rage through the capital within days.
Meanwhile, a team from an overseas-based charity organisation known as ShelterBox started handing out relief-item boxes to flood-hit Thais in Lop Buri and Ayutthaya.
Each box contains many useful items including a mosquito net, a big tent, a blanket, a portable water purifier and kitchen utensils.
Those in need of the survival kits provided by ShelterBox should call 085-140-1837.
