On Phuket, two mayors turned out to show their interest. About 120 families are affected, mostly around Nai Yang.
Some have already left their flooded homes, seeking refuge with friends or family elsewhere on the island, Marine Police said.
Rawai Mayor Aroon Soroj dangled off a back hoe to trim some grass today and Chalong Mayor Samran Jindapon waded through water to visit residents suffering from floods because of poor decisions about recent construction.
More heavy rain is predicted by meteorologists from 9pm tonight, making relief unlikely for flood-hit families at Nai Yang, Chalong and Rawai.
The flooding at all three places on Phuket is being attributed to construction projects cutting off the normal flow of rainwater.
Prime Minister Prayuth Chan-O-Cha today met the Director of the Department of Water Resources and specifically asked how authorities were coping with floods on Phuket and in the province of Korat.
Royal Thai Navy personnel combined with Marine Police to use dinghies to ferry in and out families and relief workers at Nai Yang and other inundated zones across the holiday island.
In Chalong, with water removed from three flooded areas today, authorities are on standby for more flooding overnight.
In Rawai, more rain was also expected to renew concerns about the potential for rising floodwaters.
Phuket's Governor Nisit Jansomwong is expected to visit the Nai Yang trouble-spot tonight.
