<p style="margin: 0in; margin-bottom: .0001pt;"><span style="font-size: 13.5pt; color: #454545;">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.

<p>Residents in Hawaii are bracing, yet again, for big impacts from an approaching tropical system. While Hawaii is typically successful at dodging incoming tropical storms and hurricanes, the record breaking El Niño and it's warm waters have spurred extra activity in the basin this season.<br></p><p>Nolo formed from the remnants of Tropical Depression 15E, which formed in the Eastern Pacific Basin way back on September 13th, but decayed back to a remnant low a few days later. The circulation survived as a tropical wave, which re-organized into TD15E on Wednesday, September 24th. It was upgraded to Tropical Storm Nolo later in the afternoon.</p><h1>Forecast / Impacts</h1><p>Nolo will continue to gain strength and organization as it heads north toward Hawaii through Friday, before taking a hard turn to the left over the weekend. While the core of the system is expected to remain offshore, very heavy rain, intense surf, and gusty winds are still expected to impact the islands of Hawaii. The updated cone now moves out of the Big Island.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/09/PIC 4-1790291267932.png"></p><h2>Flooding</h2><p>Flash flooding is expected, particularly on the Big Island which will see the rainfall increase through early Saturday. Flood watches have been issued for the eastern islands in the chain, which does not yet include Oahu.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-24 075029-1790259359063.png"></p><p>Rainfall totals could surpass 1-2 feet in some areas of the Big Island, especially on the eastern and northern sides, while Maui could see some rainfall totals of 10 - 20 inches.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-24 074937-1790259359065.png"></p><h2>Wind / Waves</h2><p>Tropical storm winds aren't likely for many areas in Hawaii, however the varied terrain in Hawaii could funnel gusts at certain directions, increasing wind impacts away from the center of the storm. Sustained winds near tropical storm force (39 mph and above) are possible for the southern Big Island but, if the wind field expands greatly, hurricane force winds still can't be ruled out.<img src="https://media.weathernationtv.com/app/uploads/2026/09/1-1790301375241.png"></p><p></p><p>The Big Island currently has a 20 - 70% chance of seeing tropical storm force winds, from north to south. The southern tip of the Big Island up to Kailua will see the greatest wind impacts, where residents and tourists should be prepared for debris and a better chance for power outages.<img src="https://media.weathernationtv.com/app/uploads/2026/09/1-1790301415108.png"></p><p>When should you have your home ready for the wind? While most residents aren't expected to see strong enough winds for damage to occur, loose objects should still be secured before the times in the graphic above. That's when the wind has the potential to start blowing at tropical storm force.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-24 082221-1790259752120.png"></p><p>Waves and a high risk for rip currents will be present through the weekend, diminishing next week. Swells around some beach areas could top 12 feet!</p>

Early Season Nor'easter Takes Aim at the Northeast

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!

<p><span style="color: black">The effects of El Niño are being felt along the West Coast. Everything from unusual marine life, warmer ocean temperatures and storms that can accelerate coastal erosion. The Governor of California, Gavin Newsom, has declared a state of emergency for the potential of this historic El Nino season. </span></p><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2102087880307011690" src="https://x.com/CAgovernor/status/2102087880307011690"></div><p><span style="color: black">There's another piece of the El Niño puzzle scientists are watching closely, a Kelvin wave moving through the Pacific. These waves can change sea levels and ocean conditions along the coast. Meteorologist Taban Sharifi spoke with Dr. Michael Jacox, a research oceanographer with NOAA, to better understand what these waves are and what they could mean for the West Coast during this El Nino. </span></p><div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/B6COLBbZxgE" start="0"></iframe></div><p></p><h3 style="text-align: start"><strong>What is a Kelvin wave?</strong></h3><p style="text-align: start">These waves are very different from the waves we think about crashing on the beach. These waves originate off the equator.</p><p style="text-align: start"><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-22 161553-1790115735795.png">“They are very long and they travel huge distances,” said Jacox. These waves are important in the formation of El Niño. Jacox said, “The movement of these waves helps to transmit heat from west to east.”</p><p style="text-align: start">Jacox said, “These waves themselves, it’s not like a tsunami or something that you’re going to see this big wave come in and wash over your balcony. When they come through, they can raise sea level by 6 to 12 inches. So then when you have really high tides, you have storm surge, you have these other effects, they’re happening on top of this extra 6 to 12 inches of sea level. This is sort of one ingredient in the recipe that amplifies the risk from those other factors.”</p><p style="text-align: start">The biggest impacts will come around high tides and ongoing storms, increasing the risk of sea level rise and flooding. This current Kelvin wave is expected to be near San Diego in early to mid-October. You won’t be able to see it with the naked eye, but it will be detectable through ocean measurements.</p><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2100404373692240294" src="https://x.com/WeatherNation/status/2100404373692240294"></div><p style="text-align: start">Jacox wants people to know that Kelvin waves are not new. Scientists have known about Kelvin waves for 150 years. “The Kelvin waves are one piece of El Niño. El Niño will also change storm tracks, change wind patterns, and things like that. This is one we are able to track better than we have before, and we will be on top of watching it come through,” said Jacox.</p><p style="text-align: start">Stay with WeatherNation through the hurricane season and the rest of the potential effects of El Niño on the West Coast.</p>
