Hydrologic Outlook
HYDROLOGIC OUTLOOK National Weather Service HANFORD CA 205 AM PST Mon Jan 14 2019 ...HEAVY RAINFALL AND A THREAT OF FLOODING IS LIKELY WEDNESDAY EVENING THROUGH THURSDAY IN THE SIERRA FOOTHILLS AND THE SIERRA NEVADA BELOW 7000 FEET... A Pacific storm system will bring an abundance of precipitation into mainly the higher elevations north of Kern County during midweek. Heavy rain from this storm could result in flash flooding, washed out roads, mud slides, rock slides and debris flows, particularly in the vicinity of the burn scars. Flooding is also possible near and along rivers and streams in the Sierra foothills Wednesday night through Thursday. Rain totals of 2 to 4 inches could occur in this region by Thursday evening. In the Sierra above 7,000 feet, heavy snow accumulations and hazardous winter travel is likely during mid to late week where up to 4 feet of new snow is possible. Residents in the foothills and higher elevations of the Sierra should be prepared for the possibility of life threatening flooding and closely monitor the latest National Weather Service forecasts this week for Flash Flood Watches and Warnings. If you live in a flood prone area, this would be a good time to review an emergency escape plan in the event high water or a debris flow threatens your home. Burn scars that might be impacted by heavy rain include the Ferguson burn scar, Railroad burn scar and the Pier burn scar.
