MANILA (UPDATE)— Tropical storm Agaton on Sunday afternoon maintained its strength but was moving slowly westward over the coastal waters of Leyte and Samar, the state weather bureau said.
In its 8 p.m. bulletin, PAGASA said the country's first storm was last located over the coastal waters of Lawaan, Eastern Samar, packing maximum sustained winds of 75 kilometers per hour (kph) near the center and gusts of up to 105 kph.
It made its first landfall in Calicoan Island in Guiuan town at 7:30 a.m. Sunday.
Agaton, likely to remain a tropical storm during the forecast period, is forecast to "move erratically or remain almost stationary" over east Leyte and southern part and coastal waters of Samar Island "due to weak steering environment," according to the weather agency.
"By Tuesday afternoon or evening, gradually accelerating turn east southeastward or eastward is expected as [it] undergoes a binary interaction with the incoming tropical cyclone with international name 'Malakas,'" PAGASA's latest monitoring read.
After this, the agency said the storm is forecast to weaken into a "remnant low" around Wednesday night or Thursday morning as it "assimilates circulation."
