California – Puddles spread across fields and road shoulders this morning as steady rain presses into the southern San Joaquin Valley. The ground is already soaked, and even lighter rainfall now runs off quickly, raising flooding concerns before drier winter air settles in for the weekend.
According to the National Weather Service in Hanford, a Flood Watch remains in effect through this afternoon for much of the central and southern San Joaquin Valley, including Kings, Fresno, Kern, and Tulare counties. Excessive runoff may flood creeks, streams, and low-lying roads. Urban flooding is possible where storm drains clog with debris.
Around Hanford, rain-slick pavement could slow travel along Highway 198 and nearby rural roads. Visibility may drop during heavier showers, especially late morning into early afternoon. Drivers should avoid flooded crossings and watch for water pooling in known trouble spots.
Rain tapers later today as the final system exits. By Saturday, clouds break and sunshine returns, offering a calmer stretch for weekend and holiday travel. Highs cool into the low 50s, and nights turn noticeably colder.
Saturday night brings a change in tone. Lows dip into the low 40s, with colder pockets possible in outlying areas. By Sunday night and early next week, temperatures approach the upper 30s, raising frost concerns for early morning drivers and agriculture. Any lingering moisture could create slick conditions before sunrise.
Looking ahead, meteorologists are tracking another weak system near Wednesday, December 31. Light rain is possible around New Year’s Eve, though confidence remains low. Daytime temperatures stay above freezing, but winter vigilance remains important as 2026 approaches.
Plan extra time today, avoid standing water, and prepare for colder mornings after the rain ends. Noticing flooding or slick roads where you are? Tell us what conditions look like in your area.
