Landslides, flash flooding warnings as typhoon passes over Guam

The Federal Emergency Management Agency (FEMA) is reporting two people are injured but there are no reports of casualties.

The US National Weather Service said the slow-moving category 4 storm delivered rainfall of up to 5cm per hour overnight.

The weather service said that Mawar could produce landslides, flash flooding and life-threatening storm surges.

"Treat these imminent extreme winds as if a tornado was approaching and move immediately to an interior room or shelter NOW!," the weather service in Guam warned on Wednesday evening.
