The National Weather Service has issued a Tropical Storm Watch for Guam and Rota and a typhoon watch for Saipan and Tinian. NWS meteorologist Paul Lee says Guam can expect sustained winds at 25 miles per hour with gusts around 40-45 MPH.

For Saipan and Tinian, residents there can expect sustained winds at around 60 MPH with gusts up to 80 MPH. He says the closest point would be either on Monday afternoon or during the evening. Residents are asked to prepare. Said Lee, "It's been a pretty quiet period. And we've got a few close calls within the last few years but if you haven't made any preparations, now would be the best time to go out and buy some supplies."

He added, "Be prepared for this system and any future systems that may arise or develop and impact the region."
