NWS warns of flood on Saipan, Tinian

Posted on May 22 2019


In a welcome relief to a parched Marianas region, the National Weather Service in Tiyan, Guam, issued yesterday a flood advisory for poor drainage areas on Saipan and Tinian.

Based on information received from the NWS and compiled at CNMI Emergency Operations Center-State Warning Point, doppler radar and automated rain gauges at 9:17am yesterday indicate heavy rain causing urban and small stream flooding.

“Overflowing poor drainage areas will result in minor flooding across Tinian and Saipan.

“Up to 3 inches of rain have already fallen,” the advisory from the CNMI Emergency Operations Center said.

The urban and small stream flood advisory was in effect until 12:15pm yesterday.

The public is being advised to take precautionary/preparedness actions:

Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles.

Excessive runoff from heavy rainfall will cause flooding of small creeks and streams, urban areas, and streets as well as other low-lying spots.

Additional rainfall of 1 to 2 inches is expected over the area. This additional rain will result in minor flooding.

Residents of Saipan and Tinian are being advised to be mindful of the precautionary/preparedness actions and to stay informed on the latest statements and advisories which will be available through local media sources and NOAA weather radio broadcast on 162.5 megahertz, or call CNMI EOC state warning point at 237-8000 or 664-8000, and for the Northern Islands to contact the CNMI EOC State Warning Point at high frequency single sideband radio on frequency 5.205.0.
