More Flooding Plus a Tornado Risk in California
More heavy rain (snow in the mountains) forecast. Rains have already begun over the southern two-thirds of the state. See 3:15pm radar below. In addition, there is small risk of a tornado, especially tomorrow morning, in coastal areas of Southern California, shown in dark green.
To follow the satellite moisture for Polo, keep an eye at https://cat.cira.colostate.edu/SPoRT/Layered/Advected/ALPW_Hourly.htm and especially the lower left and right hand panels of 700 to 500 and 500 to 300 hPa layers, respectively for that moisture that comes out of Polo in the tropical East Pacific and moves over Mexico and into the middle of the country and meets up with lower layers of moisture in the top two panels to spark the excessive rainfall. Also, you can keep an eye on things with our Blended Total Precipitable Water loop at https://www.ospo.noaa.gov/products/bTPW/product_animation.html?product=SUPER_NATIONAL_TPW&interval=hourly along with Experimental Advected Layer Precipitable Water Layer Vapor Transport at https://cat.cira.colostate.edu/ALPX/LVT/lvt.htm and Experimental Layer Precipitable Water Percentile Ranking at https://cat.cira.colostate.edu/ALPX/ALPW_Percentile/Percentile.html .
