- An enhanced Southwest Monsoon is forecast next week as ridging across the West weakens and begins to shift farther east. As a result, there is an increased risk of heavy precipitation and flash flooding across portions of the Desert Southwest and Four Corners.
- Increased potential for extreme heat beginning late next week over parts of the southern U.S. A moderate risk includes the Southern Plains and Lower Mississippi Valley where triple digit temperatures are possible with heat index values upwards of 105-110 deg F.
- El Nino and the MJO favor a continued active East Pacific with significant chance of tropical cyclone (TC) development from July 22-28 and additional risk of TC formation from July 29-August 4. cpc.ncep.noaa.gov/products/preci…
- El Niño continues and will strengthen through the end of the year, with a 97% chance it will persist through early spring 2027. An #ElNino Advisory remains in effect. #ENSO cpc.ncep.noaa.gov/products/analy…
