February 25, 2019— A Flash Flood Watch has been issued by the National Weather Service for the afternoon of Monday, Feb. 25 at 4 p.m. through Thursday, Feb. 27 at 4 a.m. The next storm system is expected to bring moderate to heavy rain throughout the San Francisco Bay and continuing through Tuesday evening. There is also Wind Advisory in effect for coastal and higher elevation locations through 3 a.m. Wednesday

The San Francisquito Creek is forecasted to have its largest flowrate this season, at around 2000 cfs, but that is still well short of flood stage. However, local ponding, clogged storm drains, downed tree limbs or trees, and local power outages may occur.

To report flooding issues, blocked storm drains, slides and fallen trees, call the Public Works after hours line at: (650) 329-2413.

Both Mitchell Park and Rinconada Park locations have been stocked with loose sand and 5000 filled bags this season. The filled sandbags have now been depleted, but loose sand and bags are available at these sites. There is a limit of 10 filled bags per trip for passenger cars and 20 filled bags for pickup trucks. These limits are set to promote driver safety.
All the creek monitor sensors are in place. The sensor at West Bayshore and San Francisquito Creek is currently back online. Staff has repaired the sensor and will be constantly monitoring the sensor readings and reliability.
The sensors at Waverley and at Chaucer were identified with inaccurate readings last week. Staff is evaluating these readings and will make adjustments to these sensors as needed.
