Landslides had blocked access to several villages in Sogod town, particularly Olisihan, Pancho Villa and Kahupian due to landslides in Olisihan; and Magatas, Milagroso and Benit due to landslides in Magatas.
Barangays San Juan, Kanangkaan, San Vicente were isolated due to the swelling of Subang Daku River which water level rose 2.5 meters from its normal level.
The Olisihan landslides blocked the Maharlika Highway linking Luzon and Mindanao, officials said.
Provincial emergency rescue teams also reported mudslides and fallen coconut trees blocking the roads from the villages.
Lerias said the Subang Daku River had swollen, threatening at least six other villages. She appealed over the radio for residents living on the riverside to evacuate.
Lerias estimated about 6,000 people had been affected by landslides and floods in the villages.
Another 40 families in the town of Macrohon were also evacuated after heavy flooding, she said.
"It has been raining really hard, and we had about 130 millimeters (five inches) of rainfall yesterday alone," Lerias said, adding that normal rainfall according to forecasters should be about 550 millimeters per week.
The storm came almost three months after torrential rains caused the collapse of a mountainside that engulfed the village of Guinsaugon in Saint Bernard town, leaving more than 1,000 people buried alive under a massive mudslide.

Lerias pointed out the landslides occurred in an area close to where the Guinsaugon tragedy took place.
"It was very close to Agas Agas where the landslide of Feb. 12 took place," she said. "There were no houses in the area of the landslide."
Lerias added parts of Leyte as well as the entire province of Albay in the Bicol region were also experiencing power outages since some electric posts were toppled by strong storm winds.
