Tembin is the Philippines' second deadly tropical storm this month

(CNN) A tropical storm that brought devastating flooding and landslides in the southern Philippines strengthened into a typhoon Sunday morning, according to the Philippine Atmospheric Geophysical Astronomical Services Administration.

Typhoon Tembin -- known as Vinta in the Philippines -- has killed at least 123 people, sweeping away residents and leaving communities buried in mud, authorities said.

After battering the southern island of Mindanao, Tembin slammed into another set of Philippine islands late Saturday.

Officials have given conflicting death tolls since the storm ravaged towns and displaced thousands.
