Whenever we have high pressure systems out in the west coast, the possibility of a Santa Ana winds setup becomes likely.<video src="https://media.weathernationtv.com/app/uploads/2025/10/2025-10-28 04-47-51-1761648488737.mp4" controls="true" width="100%"></video> During this phenomenon, winds head westward due to high pressures' clockwise motion. These winds will pass over the dry, desert region of the southwest and head west through the mountain passages in Southern California. During their descent, the air compresses, causing their temperatures to rise.<video src="https://media.weathernationtv.com/app/uploads/2025/10/2025-10-28 04-53-29-1761648822406.mp4" controls="true" width="100%"></video><img src="https://media.weathernationtv.com/app/uploads/2025/10/Web1-1761648886403.png">These winds are expected to bring well above-average temperatures for Southern California. In some spots, we can expect temperatures that are close to 15 degrees above average. This puts several cities in the high 80s in late October!<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web2-1761649017325.png">As a result, the National Weather Service has issued multiple heat advisories and red flag warnings across LA county and the surrounding areas.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web1-1761649090884.png"><img src="https://media.weathernationtv.com/app/uploads/2025/10/Web7-1761649119633.png">This heat will also come with the potential to break some records. Some of these forecast temperatures have Long Beach feeling like summer when most people are sharpening their skis to hit the slopes!<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web2-1761649222971.png">Stay tuned to WeatherNation where we'll keep tracking these temperatures in Southern Cali throughout this week.

Alana is the oldest of 4 siblings, all close in age, and grew up playing outside with them in all types of weather. After graduating high school, Alana moved to study at the University of British Columbia in Kelowna for a year before transferring to Dalhousie University in Halifax, Nova Scotia where she completed a Bachelor of Science in Physics and Atmospheric Science. Upon completion, Alana moved back to Toronto where she completed a post-grad degree in Meteorology at York University. After her post-grad, she went on to complete another post-grad in Broadcast Journalism - TV News at Fanshawe College in London, Ontario. During her final year of studies she had the privilege of interning with the best in the business in Canada at The Weather Network. Once she finished her internship, she got the call from small-town Denison, Texas where she accepted a job as an on-air meteorologist at KTEN-TV, right in tornado alley, covering severe weather from Sherman/Denison (North Texas) to Ada (Southern Oklahoma). After the most active tornado season Oklahoma had seen in May 2019 (105 tornadoes!) Alana is excited to join WeatherNation to cover weather all across the nation.

WEST - A series of atmospheric rivers has been responsible for wet, windy, and snowy weather in the northwestern U.S. This moisture continues to push inland through Monday. Another front has been moving onshore and will continue through Tuesday, but will mostly be focused on the state of Washington.<video src="https://media.weathernationtv.com/app/uploads/2025/10/2025-10-28 04-22-24-1761646975477.mp4" controls="true" width="100%"></video>Snowfall and rainfall totals will not be as heavy as they were this past weekend and into the early work week, but some areas should look for impacts as you head out on the roads.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web1-1761647032153.png">Another potential atmospheric river could bring wet weather for our weekend, so be sure to join on WeatherNation for the latest.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-27 160312-1761602766804.png">Be sure to join us at:50 past the hour for more details during your west regional forecast.

As our first low-pressure system bringing rain to the northeast exits, another area of low pressure will trek across the country, bringing in winds, cooler air, and rainfall.<video src="https://media.weathernationtv.com/app/uploads/2025/10/10-26 set-up-1761520578479.mp4" controls="true" width="100%"></video>There are already excessive rainfall outlooks for portions of the Mid-South and the Northeast.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web6-1761646432554.png">Although this system moves through the Plains first, the heaviest totals are likely to occur as we start to tap into more Gulf and Atlantic moisture. Forecast models bring the heaviest rainfall into portions of Kentucky, West Virginia, Virginia, and North Carolina before moving into portions of New England on Thursday.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web7-1761646473123.png">Be sure to join of live on WeatherNation for more details!

<h3>KEY MESSAGES:</h3><ul><li>Catastrophic and life-threatening flash flooding with numerous landslides for Jamaica, Haiti, the Dominican Republic, and Cuba</li><li>Destructive, devastating winds for Jamaica with the potential to cause structural failure</li><li>Life-threatening storm surge and damaging waves for Jamaica, Cuba, the Southeast Bahamas, and Turks and Caicos</li><li>Hurricane preparations for the Bahamas and Turks and Caicos should be complete by Tuesday night</li></ul>All eyes are on the Caribbean as we are now tracking the 13th named storm of the 2025 season - Melissa. In fact, we've been tracking Melissa and its origins as a tropical wave for more than a week now, and we could be watching it for another week still! Melissa has rapidly intensified into a Category 5 hurricane, with sustained winds of 175 mph, a pressure of 903 mb, and is&nbsp;slowly moving NNE at 2 mph.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web1-1761646022997.png">Melissa will hardly move, bringing catastrophic and life-threatening rainfall and mudslides to Jamaica, Hispaniola, and Cuba. Over a couple of feet of rain is possible for Hispaniola (Haiti &amp; the DR) and Jamaica.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web2-1761646094819.png">Melissa's lack of movement is due to its position between two ridges of high pressure in the mid-levels, while in the upper-levels is keeping Melissa in the Caribbean for now before picking up some steam next week. The National Hurricane Center has relayed some intense key messages for Hurricane Melissa, warning of life-threatening and catastrophic flash flooding and landslides in Jamaica and southern Hispaniola through mid-week.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1982866317859573969" src="https://x.com/NHC_Atlantic/status/1982866317859573969"></div>The latest forecast cone from the National Hurricane Center shows little forward movement over the next few days. Slow westward motion is expected through Monday morning, before turning north and northeast on Tuesday. Melissa is expected to move near or over Jamaica on Tuesday, across southeastern Cuba Tuesday night, and across the southeastern Bahamas on Wednesday, according to the NHC.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Web3-1761646183696.png">Hurricane warnings (in red) have been issued for Cuba, Jamaica, and the Bahamas, with a few tropical storm warnings also in effect for portions of Haiti, Cuba, and the Turks and Caicos. A warning is typically issued 36 hours before the anticipated first occurrence of these conditions.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-27 155300-1761602031929.png">Sea surface temperatures remain warm across the Caribbean, providing ample fuel if the wave can find a pocket of lower shear and increased moisture.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-23 060209-1761220940859.png">As many of our recently back-loaded tropical seasons have reminded us, October is not the month to let your guard down.<img src="https://media.weathernationtv.com/app/uploads/2025/10/Screenshot 2025-10-15 103336-1760546429287.png">Tune into WeatherNation for the top weather headlines for more on the tropics.
