LET'S GET TO JEFF. THE STORM COULD CREATE BIG PROBLEMS IN THE BAY AREA. >> EXACTLY. THIS STORM SYSTEM IS DEVELOPING RAPIDLY OFF SHORE RIGHT NOW, ON STORM RANGER, DOPPLER. WE HAVE A FEW AREAS OF SPOTTY RAIN. LET'S TAKE IT OUT TO THE STORM IN THE PACIFIC. IT IS GAINING MOMENTUM. SOME OF THOSE INITIAL RAIN BANDS JUST 360 MILES AWAY. WE HAVE SEEN HUGE CHANGES IN THE SPEED OF THIS STORM SYSTEM. IT'S HITCHING A RIDE ON THE JET STREAM. THE STORM TRACK AND REALLY JUST BARRELING MUCH QUICKER. SO WITH THAT STORM SYSTEM SPEEDING UP THE RAIN LINE IS ALSO MOVING MORE OFF TO THE NORTH. WE ARE DEFINITELY IN FOR SOME HEAVY BAY AREA RAIN IMPACTS. LET'S TAKE IT THROUGH THE TIMELINE. EARLY PREVIEW HERE TOMORROW MORNING INTO ABOUT 3:00 P.M. JUST SOME SPOTTY RAIN CHANCES. LOOK AT THE STORM OFF TO THE SOUTH. THIS WILL BEGIN TO MOVE RAIN IN HERE AT 8:00 TOMORROW NIGHT. THEN WE WILL BE INTO WIDESPREAD COVERAGE AT 11:00 P.M. AND THEN THIS LOOKS TO GET GOING WITH SERIOUS RAIN AT 2:00 P.M. ON SUNDAY. WE WILL BE IN TO THE SITUATION WITH THE CHANCE OF STREET FLOODING, ALSO THE CREEKS AND STREAMS RISING FAST. HERE IS THE OTHER THING. WE DIDN'T HAVE AS MUCH WITH THE LAST STORM. WIND GUSTS THAT COULD GET UP TO 60 MILES AN HOUR. QUICK PREVIEW WHEN THAT WIND STARTS TO PICK UP. WE THINK THAT WILL HAPPEN HERE BEGINNING AT 11:00 P.M. TOMORROW NIGHT. I WILL TAKE YOU THROUGH THE WIND AND THE RAIN TIMELINE. THAT'S IN ABOUT 15 MINUTES. >> WE WILL SEE YOU THEN. >>> LET'S GET TO NBC BAY AREA. THE CHP SAID IF YOU CAN STAY OFF THE ROAD THAT'S WHAT YOU SHOULD DO. FLOODING, MUDSLIDES, A REAL POSSIBILITY. >> YEAH. THOSE MUDSLIDES ABSOLUTELY. THE CALIFORNIA HIGHWAY PATROL IS WORKING WITH LAW ENFORCEMENT PARTNERS. THEY ARE KEEPING A CLOSE EYE ON THE ROADS ALL WEEKEND. ESPECIALLY THE HILLSIDES HERE IN THE EAST BAY WHERE ALL THAT DRY DIRT COULD BE PUSHED DONE PUSHED DOWN BY THE RAIN IN TO THE ROAD AND CREATE THE MUDSLIDES. THE CLOCK IS TICKING BEFORE THE NEXT BIG STORM HITS THE BAY AREA. >> THIS ISN'T LIKE OUR OTHER CALIFORNIA PROBLEMS WE HAVE EARTHQUAKE WISE WHERE YOU DON'T KNOW IT'S COMING. THIS WE HAVE A PRETTY GOOD IDEA OF SOME IMPACTFUL RAIN SO PREPARE NOW. NOW IS THE TIME. >> THAT MEANS FILLING UP SANDBAGS IF THERE IS A RISK OF FLOODING IN YOUR AREA.

THE CHP IS WARNING DRIVERS TO BE CAREFUL ON THE ROADS WHICH COULD BE FLOODED IN SOME AREAS AND THE STORM'S STRONG WINDS WILL POSE ADDITIONAL RISKS TO DRIVERS. >> AVOID BEING OUT IF YOU CAN. WE UNDERSTAND PEOPLE HAVE LIVES TO LIVE. IF YOU CAN AVOID BEING OUT IN THE HEART OF THE STORMS IT'LL BE THE SAFEST. >> ADVICE THAT PAT IS HEEDING. CANCELING THEIR WEEKEND ROAD TRIP. >> WE WERE GOING TO GO UP TO ROCK LAND BUT WE'RE GOING TO PLAY IT SAFE. >> USE THE TURN AROUND DON'T DROWN. DON'T DRIVE THROUGH IT.
