GEORGE TOWN: Flash floods hit Batu Maung and Permatang Damar Laut here after a heavy downpour since 2am on Tuesday.
At least 50 houses were flooded putting Civil Defence Department (JPAM) personnel on standby for any evacuation.
In Batu Maung, at least 20 houses were flooded with water reaching a metre high since 3am.
Penang JPAM operations officer Second Lieutenant Muhammad Aizat Abdul Ghani said 10 personnel were sent to the affected areas.
"We are monitoring the situation and are ready for any evacuation if needed," said Muhammad Aizat.
It is believed that the floods were due to clogged drains from upgrading works at a residential project along the Bayan Lepas-Batu Maung area.
Works on clearing the hill for the project had been going on for some time.
