Taban Sharifi

Monsoon Moisture Brings Flooding Across the Four Corners

Screenshot20260831164939png-1788216580658.png

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!

Wash. Rinse. Repeat. Each week there's been a storm system that ridges from the Plains into the northeast, and we've got another one headed our way. Each wave has brought severe chances and renewed flooding concerns - this one's not much different.<h1>Rainfall &amp; Flooding</h1>Repeated rounds of storms have led to swollen riverways in areas around the Midwest, like Indiana, in the past week. This week, the concern is more centered around flash flooding, when it simply rains too hard for too long. Portions of New York, Pennsylvania and New Jersey look to see some of the heavier rain totals over the next few days.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-31 133449-1788204898201.png">A slight risk for flooding has been added by the Weather Prediction Center for Wednesday. Cities like New York, Poughkeepsie, and Syracuse in New York State should stay vigilant of the flooding potential. This is especially true considering the heavy rainfall we have seen here over the last several weeks.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-31 165048-1788216654504.png"><h1>Severe Storms</h1>As these systems dive southeast out of the Great Lakes, they will have a few ingredients to turn storms severe, potentially. Right now, the timing looks a little later than usual for severe weather events. Generally favoring the afternoon and evening on Tuesday, Wednesday, or Thursday. However, data continues to point more toward the early overnight hours, with storms holding together even into daybreak. With a slow-moving system, this is subject to change, so keep up with the latest forecast over the next few days.<video src="https://media.weathernationtv.com/app/uploads/2026/08/0831-1788186321474.mp4" controls="true" width="100%"></video>The Storm Prediction Center has even issued outlooks for severe weather starting Tuesday with a SLIGHT (level 2 out of 5) risk for severe storms across New York, Pennsylvania, and New Jersey. All threats will be possible, including an isolated risk for tornadoes in some major cities!<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-31 165106-1788216670173.png">Isolated tornadoes will be possible with these storms from Ithaca, NY to Philadelphia, PA.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-31 165114-1788216681569.png">Another SLIGHT (level 2 out of 5) risk for severe weather sticks around the Northeast.

The Pacific hurricane season is showing no signs of slowing down as multiple tropical systems churn across the basin, with warm ocean temperatures and a strengthening El Nino helping create favorable conditions for development.Hurricane Karina (now a major hurricane) and Tropical Storm Lowell are among the latest systems to form over the open Pacific. Both storms are forecast to strengthen as they remain over warm water.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-31 040506-1788170724336.png">The active pattern may not end with the current systems. There is another area southwest of Mexico that could form into a tropical depression by mid to late week. Atmospheric and oceanic conditions are expected to become favorable for additional organization, giving the disturbance a high chance of tropical development over the next several days. Behind Karina and Lowell, an area of investigation Invest 95E is brewing and could spell trouble for southern California.<video src="https://media.weathernationtv.com/app/uploads/2026/08/2026-08-31 04-08-44-1788170948812.mp4" controls="true" width="100%"></video>The National Hurricane Center is investigating this potential low, Invest 95E, and some models are favoring the potential for impacts to the southwestern United States but it is still too far for us to confidently say.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-31 040925-1788170988501.png"><h1>El Nino Helping Fuel Pacific Activity</h1>The surge in tropical activity comes as El Nino continues to strengthen across the equatorial Pacific. El Nino is characterized by warmer-than-average ocean temperatures across portions of the central and eastern equatorial Pacific. Those unusually warm waters can influence weather patterns around the globe while also creating an environment that can favor tropical cyclone activity in the Pacific.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-30 070106-1788094892764.png">This year’s El Nino has already strengthened considerably, and forecasts indicate it could become exceptionally strong later this year.While the Pacific remains crowded with tropical systems, many of the current storms are expected to remain over open water. Still, with several additional areas being monitored, the active stretch of the 2026 Pacific hurricane season is far from over.Click here for more on what is happening in the Atlantic Basin:<a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/atlantic-tropics-watching-several-areas-strong-tropical-wave-next-week"> Atlantic Tropics.</a>

El Nino Powers a Party in the Pacific

During El Nino, temperatures across the Eastern Pacific Ocean become warmer, or above normal. For the hurricane season, this means an increase in tropical activity across the Eastern Pacific.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 160007-1787781615977.png">These warmer sea surface temperatures also mean an increase in shark activity for Southern California beaches. Meteorologist Taban Sharifi spoke to Dr. Christopher Lowe, professor of marine biology and director of the Shark Lab at California State University, Long Beach on how El Nino brings changes to marine life along the coast.<div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/1FcXy4BQcgA" start="0"></iframe></div>As the waters continue to warm through the Fall, Dr. Lowe talked about the changing species that will be seen across the Southern California waters that are not typically there. This includes hammerhead sharks, whale sharks, and even manta rays. This also includes white sharks. The water farther south will get too warm for the white sharks, that are normally off the Baha of California, and they will begin to push north. Dr. Lowe said, "It's going to push those juvenile white sharks that are normally in Mexico into Southern California waters." This is something they have already started to see happen during July and August of this year, and the numbers of these sharks are increasing. Dr. Lowe said the sharks could reach as far north as Santa Cruz, CA.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 155905-1787784580682.png">There's a sweet spot for water temperatures for these sharks that sits between 64°-72°. Above 82° is when sharks begin to move north. Currently, water temperatures in the Eastern Pacific are significantly warmer than that 82° threshold.A message to beach goers: "Believe it or not, having all those white sharks off that beach might actually keep people safer. Because they are eating sting rays, there are fewer sting rays that might hurt people," said Dr. Lowe.Watch the full interview for more on how close these sharks get to the coastline and how scientists track their behavior.

The wait is finally over. After 106 straight days with no measurable rainfall in Tucson, Arizona the city has officially picked up at least a tenth of an inch. Ahhhh, refreshing!

<img class="alignnone size-large wp-image-92665" src="https://media.weathernationtv.com/app/uploads/2018/06/Capture2-10-728x408.jpg" alt="" width="728" height="408" />

A preliminary rainfall report for Tucson showed 0.10" of rainfall as of 9 p.m. Friday. It was still raining around the city at the time of this article, so that daily rainfall report will likely be just a tad higher. Nonetheless, it's the first measurable rainfall since the city received 0.20" on February 28 this year!

https://twitter.com/NWSTucson/status/1007787766271397889

While a little technical, yes; the image above shows the weather balloon launch from Friday evening in Tucson. Meteorologists noted the highest precipitable water value for June 15! Commonly referred to as Pwat, it's a measurement of the amount of moisture in the atmosphere. This specific moisture Friday was coming in from the tropical remnants of "Bud."

<img class="size-large wp-image-92666" src="https://media.weathernationtv.com/app/uploads/2018/06/Capture3-11-728x408.jpg" alt="" width="728" height="408" /> These are 24-hour rainfall reports ending Friday evening, June 15.

The remnant moisture from Post-Tropical-Cyclone Bud will stir up additional rain showers and thunderstorms across the Southwest this weekend.

Nearby Phoenix also had a milestone Friday, reaching a dew point temperature (also a measure of moisture) of 60 degrees!

https://twitter.com/SteveGlazier/status/1007753810171723776

The tropical moisture is returning at a time that usually signifies the beginning of the monsoon season in the Southwest U.S. When the Southwest heats up continuously and rises into the 100's daily, an onshore wind begins to develop from the nearby, cooler Pacific and Gulf of Mexico. This helps to draw in moisture and bring rain more often. Take a look at the monthly rainfall summary for Tucson.
