Tropical Storm Octave formed earlier on Tuesday in the Eastern Pacific. This remains a tropical storm and is forecast to meander off to the west.<img src="https://media.weathernationtv.com/app/uploads/2025/10/web1-1759424726669.png">The good news with Octave is that the NHC has good confidence it will likely stay out to sea. The NHC's latest update has Octave becoming a Category 1 Hurricane, although nothing more with hostile atmospheric conditions is expected.<img src="https://media.weathernationtv.com/app/uploads/2025/10/web5-1759424773795.png">Right behind Octave, we have one more wave trying to form sometime later this week.<img src="https://media.weathernationtv.com/app/uploads/2025/10/web3-1759424820709.png">The next name up on the Pacific hurricane season names list is Priscilla.<img src="https://media.weathernationtv.com/app/uploads/2025/09/web3-1759251694412.png">Reminder that we're getting over the final secondary peak of the Pacific hurricane season. It's important to continue to stay updated all the way throughout!<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-29 154651-1759182418223.png">Stay tuned on WeatherNation for the latest!

Imelda is now a Post-Tropical Cyclone as it quickly moves east-northeast, away from Bermuda. That means it is no longer getting it's energy from tropical processes. According to the National Hurricane Center: "Visible satellite images and global model fields indicate that a front extends into the center of the cyclone from the east-northeast, while another frontal feature has developed to the south of the cyclone." Fronts are consistent with extra-tropical cyclones. It still remains strong with winds at category one strength, however.KEY MESSAGES:<ul><li>Imelda is weakening as it moves through the Atlantic</li><li>Imelda pushed past Bermuda overnight. Tropical alerts have been cancelled.</li><li>Swells and high surf from Imelda are expected to impact the U.S. East Coast over the next several days</li></ul><img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-02 091030-1759417846055.png"><h1>Coastal Flood Potential</h1>Life-threatening rip currents remain possible, as well as coastal flooding with inundation of 2 to 3 feet above ground level. This flooding can move inland, impacting homes and businesses. Dangerous swim conditions will also be a concern. Please listen to local authorities and avoid swimming if possible, as rip currents can be deadly.<img src="https://media.weathernationtv.com/app/uploads/2025/10/web7-1759424627017.png"><h1>Waves &amp; Rip Currents</h1>The coastline from Florida to North Carolina is highlighted for high surf. Some wave heights could reach up to 11 feet.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-01 130354-1759345444733.png"><img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-02 091224-1759417958503.png">A high threat for rip currents remains likely over the next few days. Check the flags at the beaches to make sure conditions are safe enough where you are if you're planning to get into the water.<h2>What's Next For the Atlantic</h2>The NHC is monitoring another tropical wave over the central tropical Atlantic that is expected to move off the coast of Africa in the next day or two. There is currently a low chance of tropical formation.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web 10-1759400620555.png">

WEST - As a trough of low pressure lingers off the west coast, a few fronts have pushed into the western U.S and across the Intermountain West. Our forecast models indicate scattered rain moving into states such as Idaho, Nevada, and Utah through the end of the week, with higher elevations expected to receive some snowfall.<video src="https://media.weathernationtv.com/app/uploads/2025/10/2025-10-02 13-00-54-1759424489138.mp4" controls="true" width="100%"></video>Due to their high moisture content, these showers will be more efficient at producing rainfall, resulting in higher totals. Some areas could pick up a few inches of rainfall, which could bring on a low-end flooding threat. Excessive rainfall outlooks issued for the are Thursday and Friday.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web2-1759402402070.png"><img src="https://media.weathernationtv.com/app/uploads/2025/10/Web1-1759402410838.png">Not all the precipitation may fall as rain! Longer range models are spitting out decent snow totals across the Cascades and the Sawtooth Ranges of central Idaho! Excessive rainfall outlooks continue through Thursday.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web5-1759412251078.png">More details on your Western Regional Forecast can always be found :50 past the hour on WeatherNation.

Tropical activity in the Atlantic has increased significantly over the last week. We're now tracking two named storms, Imelda and Humberto. On Saturday, Humberto reached Category 5 status, with sustained winds topping out at 160 mph! Since then, it has backed off to 80 mph winds, making it a category 1 storm.<h1>LOOKING BACK</h1>Humberto was named a week ago, last Wednesday afternoon, and gained hurricane status early Friday morning. This is the first time in nearly 100 years that we have had 2 Category 5 hurricanes in back-to-back seasons!<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-30 203358-1759286043566.png">We are now past the climatological peak of Atlantic Hurricane Season, but still have a ways to go for the season. For being such a quiet season, the normal amount of Accumulated Cyclone Energy, a metric to quantify activity, is not far off. Two category 5 hurricanes will boost those numbers, though.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-01 091802-1759331890905.png">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>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.

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.

A cold has been slowly progressing across the country, bringing rain and gusty winds along with it. The front will continue to approach the East Coast to tend the week, spurring heavy showers and a few severe storms.Damaging winds are the primary concern here as we head into Thursday from Connecticut through Georgia (top of page). Isolated tornadoes are also possible, primarily in the Northeast.<img src="https://media.weathernationtv.com/app/uploads/2025/09/PIC 3-1758827812988.jpg">Storms will follow along and ahead of the frontal boundary through the end of the work week. For now, Friday remains under a general thunderstorm risk.<video src="https://media.weathernationtv.com/app/uploads/2025/09/FORECAST-1758827797862.mp4" controls="true" width="100%"></video> The other concern is the threat of flooding. With multiple rounds of showers and storms rivers, creeks, and streams will already be swollen which could keep the risk elevated through Thursday. <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-25 063248-1758803576034.png"> Tune in to WeatherNation live for more updates.

Rain finally moves into areas that have been drought-stricken. There will be a chance of repeated storms and downpours across the mid-south through the northeast.&nbsp; A cold front will be pushing eastward across the eastern portions of the United States, where most of these storms will develop along the front.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-24 084229-1758724971383.png">Cities like Atlanta have not received that much rain. Atlanta has received only 0.02 inches of rainfall for the month of September. This set the record for the driest September since record-keeping.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-24 084320-1758725011813.png">Over the next several days, the Weather Prediction Center has issued excessive rainfall outlooks. A slight risk has been issued for&nbsp;Tennessee, Kentucky, West Virginia, and the southern portions of Ohio.

An aurora could be visible tonight for the northern tier of the United States as a Coronal Mass Ejection (CME) event peaks solar radiation! The best time to view the aurora will be 4 - 7 AM Central Time, but the earlier the better due to the dark conditions. Overnight will be a new moon so very little moonlight will detract from the aurora visibility.According to the <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.gi.alaska.edu/monitors/aurora-forecast">Geophysical Institute</a> at the University of Alaska Fairbanks, the aurora will be visible through Tuesday morning from "Helena [MT to] Minneapolis [MN to] Milwaukee [WI to] Bay City, Toronto [Canada to] Montpelier [Vermont]" The aurora may even be visible along the horizon for Boise, ID, Lincoln, NE, Indianapolis, IN and Annapolis, MD!<img src="https://media.weathernationtv.com/app/uploads/2023/09/tonights_static_viewline_forecast-1695054707785.png">The reason for the aurora is from a Coronal Mass Ejection (CME) that is expected on Tuesday. The "K-index" is used to "characterize the magnitude of geomagnetic storms" according to NOAA. Tuesday's K-index will be on the order of mid-levels. According to NOAA, "Kp is an excellent indicator of disturbances in the Earth's magnetic field and is used by [space weather prediction center] to decide whether geomagnetic alerts and warnings need to be issued for users who are affected by these disturbances".<img src="https://media.weathernationtv.com/app/uploads/2023/09/estimated-planetary-k-in-1695054555994.png">For more on geomagnetic storms and potential impacts for the U.S., watch Meteorologist Alana Camera as she heads inside the Space Weather Prediction Center located in Boulder, CO!<div class="fb-post" data-href="https://www.facebook.com/watch/?v=617034086665143" data-width="500" src="https://www.facebook.com/watch/?v=617034086665143" style="display: flex; justify-content: center"></div>
