Flood advisory active for San Mateo County early Sunday morning caused by substantial rain

Heavy Rain Batters San Mateo County, NWS Issues Flood Advisory

A flood advisory has been issued for San Francisco and San Mateo counties early Sunday morning, as a substantial amount of rain pounds the area. The National Weather Service (NWS) warned that flooding is expected in low-lying areas, prompting residents to exercise caution when encountering flooded roads.

According to the NWS, "Flooding caused by excessive rainfall is expected" in the region. Minor flooding is forecasted in poor drainage areas, and officials advise motorists to turn around and not try to drive through floodwaters, as most flood-related deaths occur in vehicles.

The flood advisory is set to expire at 5:15 a.m., but residents are urged to stay vigilant and be prepared for further heavy rain showers. The NWS also issued flash flood watches for the area, warning that sudden and violent inundations can develop within minutes to hours, even in areas not currently experiencing rainfall.

As the storm continues to batter the region, residents are advised to take precautions to protect themselves and their property. This includes seeking higher ground, following evacuation orders, disconnecting utilities and appliances, and steering clear of flooded basements and submerged areas.

When driving through heavy rain, slow down, maintain a safe distance from large vehicles, and prioritize visibility. The NWS also warns that roads can be slippery during the initial half-hour of rain and advises drivers to exercise heightened caution.

Stay tuned for further updates on the storm's progress and follow the latest weather advisories from the National Weather Service.
 
omg, gotta be careful out there 🌧️😬... heavy rain is no joke, especially when it comes to flooding. i know some ppl might be thinking of taking a drive or venturing out during this time, but trust me, it's just not worth the risk πŸ€¦β€β™‚οΈ. those floodwaters can be so deep and fast-moving, it's like a different world altogether 🌊. i'm all for getting outside when the weather clears up, but for now, let's all just stay safe indoors β˜•οΈπŸ“Ί and keep an eye on each other 🀝.
 
ugh this is getting serious... heavy rain already causing flooding issues, and it's still early morning? what if the flood advisory doesn't hold true and more severe flooding happens later? people are advised to exercise caution, but isn't that just a normal thing to do when there's a flood warning in the first place? πŸ€”πŸ’§ also, shouldn't the roads be cleared or treated with salt/sand before it gets this bad? 🚧😬
 
"Life is what happens to you while you're busy making other plans." 😊 It's like Mother Nature decided to take a wild detour, pouring rain all over San Mateo County. Now it's up to us to stay safe and make our own plan B – maybe it's seeking higher ground or unplugging those utilities? πŸš¨πŸ”‹
 
Ugh, great just what we need... more flooding 🌨️. Like, who thought it was a good idea to build homes in areas that are basically just giant puddles waiting to happen? I mean, I get it, San Mateo County is beautiful and all, but can't they just, like, plan ahead for the rain? πŸ€·β€β™€οΈ And seriously, why do we need multiple flood advisories? Can't they just make up their minds on when it's safe to venture out again? 😩 Also, side note, I'm starting to think those "flash flood watches" are just a fancy way of saying "we have no idea what's going on". πŸ€”
 
Ugh, this is just like when I was a kid and my parents used to get those flood warnings every few years... remember how we'd always have to move our stuff to higher ground? πŸ€” Anyway, it's crazy that they're still having issues with flooding in the Bay Area. I mean, didn't they fix the drainage system back in the day? πŸ˜• And now they're telling people to stay vigilant and be prepared... like we haven't been through this before. πŸ™„ Still, gotta respect the NWS for keeping us in the loop. Just hope everyone stays safe out there! πŸ’¦
 
OMG, this is just like what happened when I was a kid in '02 🌨️, we'd get these crazy rainstorms and the whole neighborhood would flood like crazy! My friend's house was literally underwater for days, poor guy had to deal with that for ages 😩. Now, it seems like they're saying the same thing about people driving through flooded roads, "don't do it, just turn around" πŸš—. And now they're telling us to be vigilant and stuff... back then we didn't have all these warnings and apps, we just kinda dealt with it πŸ“±. Anyways, just hope everyone stays safe out there! πŸ’•
 
ugh flooding is like the worst πŸ€• just thinking about driving through flooded roads gives me anxiety, like what if you get stuck? or worse, gets swept away? 🚨 anyway, can we pls focus on something else for a sec? this rain is giving me the blues, all that grey and gloomy outside kinda sucks the energy outta u, like literally, just got back to my flat after a day out and it's still pouring 🌨️
 
Ugh, another rainy day in Cali 😩. I mean, I love a good rainstorm as much as the next person, but can't we just get some sunshine already? The flooding is definitely a concern, especially with all the new developments and homes being built in low-lying areas. It's crazy to think about how quickly things can go from "oh look at that cute little creek" to "whoa, we've got water everywhere". And don't even get me started on the traffic - slow down, everyone! πŸš—πŸ’¨
 
Ugh dont wanna hear this again San Mateo county is so flooded every year 😩 its like the skies are crying or something who needs that much rain anyway? πŸ€·β€β™‚οΈ i swear if im stuck in traffic with my windshield wipers on full blast ill lose it πŸ’₯ shouldnt they just bring like, a big umbrella or somethin to keep us dry? πŸŒ‚ and whats up with the NWS? always warning about floods but never actually doin anything about it πŸ™„
 
OMG u gotta stay inside today 🀯! This rain is crazy!! 😩 I mean, I know we need water and all but can't it just chill? 😴 The roads r gonna be super slippery 2 b4 n after the first half hour so u gotta slow down & be careful 2 drive 3n San Mateo co. πŸš—πŸŒ‚οΈ My aunties in Millbrae said their yard's already flooded πŸ€¦β€β™€οΈ what if it gets worse? β›ˆοΈ I'm def stocking up on supplies & just chillin indoors πŸ˜΄πŸ’‘
 
ugh i cant even right now 🀯 the thought of all that water just pouring down is giving me anxiety its like the whole world outside is screaming at us to stay inside but what if you need something? what if u have no choice? i feel so stuck and helpless when it comes to these kinds of situations my grandma used to tell me stories about her village in philippine getting hit by typhoons and she always had this saying "you can't control the storm but you can prepare for it" i wish that were true right now
 
omg is this 2025 already i thought it was still 2024 lol why do we always have to worry about floods in california? can't we just get some sunshine around here? btw, has anyone tried those new electric bikes that just came out? heard they're super cool πŸš΄β€β™‚οΈπŸ˜Ž
 
omg is it always like this in california? heavy rain just shows up out of nowhere 🌧️😨 i feel bad for all those poor people who have to deal with flooded roads every other week... they should really find a way to predict these storms better β°πŸ’‘
 
omg i dont wanna go to school tomorrow lol, heavy rain is so annoying! i was planning to drive to santa cruz with my friends but now we have to consider the flooding 🌨️😬 i wish they would fix our school's drainage system, it always gets flooded during rainy days 😩 anyway, gotta stay safe and not take any unnecessary risks πŸ’ͺ lets just hope the rain goes away by tomorrow morning 🌞
 
Floods got me thinkin' about the fleeting nature of our reality... One minute we're goin' about our daily lives, the next, we're wadin' through chest-deep water like it's no big deal 😬. It's a harsh reminder that Mother Nature ain't playin' by our rules, and sometimes we gotta get outta her way. I mean, think about it, floods can be beautiful, too - all that water creatin' new paths, washin' away the old... but at what cost? 🌊 Our homes, our belongings, our sense of security... it's all just temporary, like a ripple on the surface of a pond. We'd better appreciate the little things while we can 'cause when the storm hits, there ain't no shelters to hide in, only our wits and whatever we can scrounge up 🌴.
 
OMG, this is crazy! 🌨️ I'm so worried about all those people who are gonna get stuck in their cars or homes cuz of floodwaters. Like, can't we just prepare for these kinds of situations instead of being all surprised when they happen? πŸ€¦β€β™€οΈ And what's up with the NWS not having better systems in place to warn us sooner? I know it's not their fault, but still... We need to do better! πŸ’‘ Let's get some investment into infrastructure and disaster relief, ASAP! πŸ’ΈπŸ’–
 
I'm worried about all those homes in San Mateo County that are prone to flooding 🌧️... The NWS is right, most flood-related deaths happen when people try to drive through flooded roads, so it's really important for drivers to exercise caution and just turn around if they see water on the road. I hope everyone stays safe and dry out there πŸ’¦... It's also a good reminder to check in on our neighbors who might be more vulnerable to flooding, like the elderly or those with disabilities 🀝
 
Ugh I was saying this earlier πŸ€¦β€β™‚οΈ, San Mateo County needs better drainage systems, all these heavy rains are causing so much damage to homes and roads... like remember that flood last year? It was a disaster! And now they're issuing another flood advisory, it's getting old. Can't we just get some decent rain management system in place? πŸ€”πŸ’§
 
πŸŒ‚οΈ this is so crazy, i was just thinking about how some ppl forget that its california and not vegas or something, all that water comes down and u gotta be ready, like back in 2017 when we had the flood alert too, remember those roads were flooded for days lol, but seriously, slow down when driving through rain, dont try to drive through floodwaters, its not worth it πŸš—πŸ’¦
