Flooding may occur in poor drainage and urban areas. * ADDITIONAL DETAILS... - A broad tropical disturbance will interact with a shear line, impacting the Marianas starting late tonight, through the weekend, and much of the coming week. Several rounds of heavy to very heavy rainfall will be possible during this time frame. This could lead to 5 to 10 inches of rain across the Marianas with locally heavy amounts. Due to the wet antecedents from early this week, the conditions for flash flooding could be met at a lower threshold. - http://www.weather.gov/safety/flood
