Ty Chaba is currently impacting Guam and the Marianas right now, expected to potentially cross over the island chain in the next day or so.

NWS/Guam's radar is capturing the typhoon on it's long-range radar, as you can follow through this link:

Pretty cool stuff, particularly considering radar observations of typhoons aren't all that common - or at least aren't readily available.
