HYDROLOGIC OUTLOOK
National Weather Service HANFORD CA
1034 AM PST Fri Mar 1 2019

...HEAVY RAINFALL AND A THREAT OF FLOODING IS POSSIBLE OVER
PARTS OF THE CENTRAL CALIFORNIA INTERIOR BY THE MIDDLE OF NEXT
WEEK...

A COUPLE MORE STORM SYSTEMS WILL IMPACT THE CENTRAL CALIFORNIA
INTERIOR DURING THE NEXT 7 DAYS. THE NEXT STORM WILL TRACK
THROUGH THE REGION FROM THIS EVENING THROUGH SATURDAY AND IS NOT
EXPECTED TO BRING MORE THAN LOCALIZED NUISANCE FLOODING. THE NEXT
STORM SYSTEM COULD BRING AN ABUNDANCE OF TROPICAL MOISTURE INTO
CENTRAL CALIFORNIA FROM TUESDAY THROUGH WEDNESDAY ACCOMPANIED WITH
SUBSTANTIAL PRECIPITATION AND A HIGHER THREAT OF SIGNIFICANT
FLOODING...ESPECIALLY IN THE FOOTHILLS AND MOUNTAINS. MILD AIR
ASSOCIATED WITH THIS STORM WILL KEEP SNOW LEVELS ABOVE 8000 FEET
AND POSSIBLY 9000 FEET DURING MUCH OF THIS PERIOD.

HISTORICALLY...HEAVY RAIN TOTALS CAN BRING LOCALIZED FLASH
FLOODING AND ASSOCIATED IMPACTS SUCH AS WASHED OUT ROADS AND
BRIDGES...MUD SLIDES...ROCK SLIDES AND DEBRIS FLOWS...PARTICULARLY
IN THE VICINITY OF THE BURN SCARS. MINOR STREET FLOODING CAN OCCUR
IN URBAN AREAS AND IN OTHER AREAS OF NORMALLY POOR DRAINAGE.

RISING WATER LEVELS ARE ANTICIPATED ON RIVERS AND STREAMS DURING
THE MIDDLE OF NEXT WEEK...ESPECIALLY OVER THE HIGHER TERRAIN
WHERE THE COMBINATION OF RAIN AND MELTING SNOW WILL ACCELERATE
RUNOFF.

THERE IS NOW A POSSIBILITY THAT THE HEAVIEST RAIN FROM THESE
STORMS COULD TARGET SOUTHERN CALIFORNIA. RATHER THAN FOCUS ON
THE EXACT TRACK OF THIS STORM...IT IS IMPORTANT TO KEEP IN MIND
THAT THE GROUND IS NOW SATURATED ACROSS MUCH OF THE CENTRAL
CALIFORNIA INTERIOR SO ADDITIONAL RAINFALL COMBINED WITH SIERRA
SNOWMELT FROM THE NEXT TWO STORM SYSTEMS WILL MORE EASILY
INCREASE THE VULNERABILITY OF FLOODING.

RESIDENTS SHOULD KEEP IN MIND THAT AREAS THAT HAVE RECENTLY
FLOODED OR NORMALLY FLOOD DURING HEAVY RAIN EVENTS COULD EASILY
FLOOD AGAIN. IF YOU LIVE IN A FLOOD PRONE AREA OR NEAR STREAMS AND
RIVERS...THIS WOULD BE A GOOD TIME TO PREPARE OR HAVE AN
EVACUATION PLAN IN PLACE IN THE EVENT HIGH WATER BECOMES A THREAT
TO YOUR SAFETY.
