Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

While the Atlantic has been relatively quiet this season, the Eastern Pacific has been more active, particularly in recent months. Early Saturday morning, Mario dissipated southwest of the Baja Peninsula, only to reemerge Sunday morning as a tropical storm. It has since lost tropical storm status but it's remnant moisture is bringing flood chances to California. <video src="https://media.weathernationtv.com/app/uploads/2025/09/2025-09-18 04-55-48-1758193214237.mp4" controls="true" width="100%"></video>Mario weakened upon encountering cooler sea surface temperatures and enhanced shear. It became post-tropical once and for all Tuesday night. The leftover moisture from Mario is moving north across California over the next few days with an attendant flooding threat.<video src="https://media.weathernationtv.com/app/uploads/2025/09/2025-09-18 05-01-24-1758193318979.mp4" controls="true" width="100%"></video>The rain will be a welcome sight for many in California. Downtown LA hasn't seen rain since the beginning of JUNE! Unfortunately the rain also comes with a threat for flooding, particularly in the mountains and deserts.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-17 104048-1758127280118.png">The Baron forecast model depicts pockets of 3-4 inches of rain through Friday, especially in the mountains around Southern California and in the Sierra. <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-18 050000-1758193278094.png">The tropical nature of the rainfall is likely to lead to some flooding. The southern Central Valley out to the Colorado River, including much of southern California, is included in a Slight Risk (Level 2) Excessive Rainfall Outlook on Thursday, while the higher threat shifts north to the Sierra on Friday. Areas that have seen wildfire activity in recent years or this year will have a higher flood risk.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-18 045824-1758193119328.png"><img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-18 045828-1758193129903.png">

Mario Sends Tropical Moisture to California, Flooding Possible

We are now a week after the climatological peak of Atlantic Hurricane Season. Conditions are slowly becoming more active in the Atlantic as Gabrielle is churning in the Central Atlantic while another tropical wave is expected to emerge from western Africa this weekend. <h1>Gabrielle</h1>Tropical Storm Gabrielle is in the Central Atlantic and is expected to strengthen in the coming days as turns northeast this weekend, likely to pass Bermuda to the east. People with interests in Bermuda should monitor this storm, as direct and indirect impacts are still possible.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-18 044732-1758192491294.png">On Wednesday, the NHC was highlighting two tropical waves emerging from Africa, but one of those waves is not likely to develop so that area has been removed. The remaining region highlights the potential development for a wave expected to move off the coast of Africa this weekend. Conditions will be hostile for this tropical wave for some time as Saharan Dust (dry air) is expected to continue to surge in this area.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-18 044825-1758192515950.png"><video src="https://media.weathernationtv.com/app/uploads/2025/09/New Baron Video 3-1758140698761.mp4" controls="true" width="100%"></video>Do not let your guard down! September is historically the peak of hurricane season, and ocean conditions remain favorable for additional development. However, the NHC urges residents along the Atlantic basin to monitor updates closely.<div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/W2bhqfX0B0A" start="0"></iframe></div>What is slightly concerning are the water temperatures in the Gulf. Right now, they are 1°C warmer than they usually are for this time of the year. That being said, it's been tough to get anything over those warm waters so far this season-let's hope that continues.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-13 051452-1757762098585.jpg">As always, preparedness is key. Whether or not this particular system develops into a named storm, it serves as a reminder that the Atlantic remains active and that the window for tropical threats is far from closed.

Gabrielle Churns in the Atlantic, Another Tropical Wave Emerges

CENTRAL U.S - A trough that came in from the Pacific, moved over the Rockies, and is now in the Plains has been responsible for severe storms across the High Plains. It's now pushing into the Midwest and Southern Plains, ushering a slow-moving cold front through the area.Related: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/north-dakota-breaks-yearly-tornado-record">Dakota Tornado Record Falls Over the Weekend</a>The front is moving southward, bringing the threat of more hailstones and damaging winds. A level one risk (marginal) is in effect for Thursday from Iowa to the Panhandle of Texas.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-18 053127-1758195099369.png">Storms are expected to continue for most of Thursday along the frontal boundary, with more intense storms in the afternoon as daytime heating provides additional energy and lift. Scattered storms will continue along the front overnight into Friday, with a few more heavy downpours expected Friday afternoon.<video src="https://media.weathernationtv.com/app/uploads/2025/09/2025-09-18 05-37-12-1758195479937.mp4" controls="true" width="100%"></video>Rainfall rates could surpass 1-2" per hour in these slow moving thunderstorms, resulting in pockets of 2-4 inches of accumulation. This could lead to isolated flash flooding.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-17 192042-1758158454292.png">The WPC has issued excessive rainfall outlooks for this isolated flood chance for Thursday and Friday, between west Texas and northern Mississippi.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-18 053746-1758195612299.png">Always use caution with flood waters, as you never know how deep the water is.

Grab the pumpkin spice and apple cider donuts, fall foliage has started to grace some areas across the United States, with more developing this week! The latest forecast from <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.explorefall.com/fall-foliage-map">Explore Fall</a> (top of page) shows peak color emerging across the higher elevations of the Colorado Rockies, and the Beartooth and Wind River Ranges in Wyoming over the next seven days (September 15th - 21st). <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-17 190824-1758158004265.png">Color has already been showing some for areas in the map above (yellow and orange areas), mostly in the Rockies and Cascades. In fact, we've seen the Bigtooth Maples change quite a bit in the Wasatch Mountains near Salt Lake City!<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1964055938010067402" src="https://x.com/WeatherNation/status/1964055938010067402"></div>The most 30 days before the appearance of fall color are the most important for vibrancy during the peak season, but drought conditions can also lead to more muted color or variable conditions.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-08 105237-1757350392233.png">For great fall color, sunny days with cool, crisp nights are preferable.

The dry time has been a little hard to enjoy the last week or two in South Florida. While this is the rainy season, and we're making up for a slow start to it, you can still roll your eyes at what the extended forecasts have looked like recently. In fact, some spots in South Florida have already had their wettest start to September, including Miami.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-16 163631-1758062210080.png">On the other end of the spectrum, some northern Florida spots have really missed out, making it the driest start to September in areas such as Gainesville and Tallahassee.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-16 163641-1758062216443.png">So why? Just because Florida likes to have the most fun? Well, actually, a frontal boundary keeps these storms coming for days. While we've had a couple of days of relief, more moisture is in the forecast for South Florida.That, along with a TON of moisture to work with, is attempting to catch up some drought-stricken areas of the Sunshine State. The Drought Monitor updated on Thursday and had some pretty sizeable improvements in South Florida.<video src="https://media.weathernationtv.com/app/uploads/2025/09/2025-09-11 09-39-57-1757605257541.mp4" controls="true" width="100%"></video>So while it might be easy to complain about beach plans constantly getting ruined, it has its benefits. Our biggest concern is the lightning threat associated with any Florida thunderstorm, but especially this time of year, with people outdoors. Anytime it rains this heavily, of course, the flash flooding threat will be there as well. Some areas could receive another 3-5 inches, or even more, before the rain chances start to back off next week.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-17 205021-1758163841398.png">

Florida Rainfall: Nuisance or Beneficial?

Did you see them? Many might have had better things to do this weekend but if you were paying attention to Space Weather, you got a treat! NOAA's Space Weather Prediction Center upped the expectation late last night, with some dazzling results.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1967422118729273403" src="https://x.com/NWSSWPC/status/1967422118729273403"></div>The problem for many in the plains was cloud-cover, with evening storms making it difficult to see the lights behind the lightning, but some were lucky to sneak between the clouds.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-15 092335-1757950156965.png">Granted, it might have been difficult to see with the naked eye. Many of the photos we've seen have mentioned a long exposure that was needed to see the fun. Either way, it's gorgeous if you can figure it out.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-15 092324-1757950271340.png">While it wasn't the most robust solar storm we've seen in the past 2 years, it was well worth it for some! We're not expecting another show, however.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-15 134825-1757965711698.png">

A strong upper-level trough along with monsoonal moisture advecting northward continues to hone in on Western Colorado, SE Utah, and New Mexico. Both a flood threat and isolated severe thunderstorms will be possible. There are risks for excessive rainfall and flooding over the next few days. The risks are very isolated in the threat of flooding, but it is still something to pay attention to.<video src="https://media.weathernationtv.com/app/uploads/2025/09/09-14 rsc wpcs-1757878358375.mp4" controls="true" width="100%"></video>The Storm Prediction Center has the risk for strong storms stretching from North Dakota to Texas, but here we will discuss the threat for the southern Plains and Texas.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-14 133029-1757878277064.png">The latest model data suggest that the heaviest rain will be focused over parts of West Texas and the Central Plains as the disturbance keeps moving east. With upper-level support, some thunderstorms may become organized with a severe threat. Straight-line damaging winds would be the main hazard through the weekend but a few tornadoes are possible.<video src="https://media.weathernationtv.com/app/uploads/2025/09/09-14 rsc-1757878300010.mp4" controls="true" width="100%"></video>Stay with WeatherNation for the latest updates.

Isaac could redevelop into a tropical depression or storm once more. We can't completely let our guard down just yet. The National Hurricane Center is giving Isaac's remnants a low chance of tropical development in the next few days.
