An upper level low will will continue to influence storms in the Gulf and Bahamas through Monday. With the lack of a strong synoptic surface forcing mechanism, predictability as to where and when heavy rain will fall remains low. However, the environment continues to support the potential for heavy rainfall and slow moving cells. * WHAT...Heavy rain may cause, or worsen ongoing urban and street flooding. * WHERE...All of South Florida * WHEN...Through Monday evening. * IMPACTS...Isolated to scattered areas of flash flooding will be possible, with the main impact being street flooding, road closures, and limited impact to structures in flood prone areas. * ADDITIONAL DETAILS... - Pockets of very heavy rainfall resulted in localized flash flooding on Sunday and those areas, and others, have the potential to be impacted again on Monday. Forecast amounts look very similar to yesterday, with common amounts of 1 to 3 inches where showers and storms occur. Scattered locations around south Florida may see closer to 3 to 5 inches of rain. The more isolated high end amounts have the potential to peak around 6 to 9 inches. These amounts could accumulate rather quickly, on the order of 2 to 4 hours. - http://www.weather.gov/safety/flood
