You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.

* WHAT...Flash flooding caused by excessive rainfall continues to be possible. * WHERE...Guam and Rota. * WHEN...Through late tonight. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. * ADDITIONAL DETAILS... - While showers remain limited this afternoon, a persistent monsoon disturbance to the northeast of the region will allow a wet southwesterly pattern to develop across the region this evening, bringing higher likelihood for locally heavy showers that could produce flash flooding over the next couple of days. As such, the Flash Flood Watch remains in effect and could be extended and potentially include Tinian and Saipan, if conditions warrant. - http://www.weather.gov/safety/flood
