Derek vam dam is with us with some new news. Were going to start with the radar over the western half of the united states. You can see weve had a significant amount of rain across this region, especially near the los angeles area. And i bring this up because were getting some information from the Ventura County fire department, an area about an hour north of Los Angeles Maz actually had a mudslide occur within the past few hours. One house was impacted directly. A man was trapped inside of the house. But he was located and removed and is safe along with his wife. 11 homes have been evacuated as a precaution. You can see the rainfall moving through the area. It has been a drought stricken season for much of california, in fact all of california. Los angeles, the last time it had any measurable rainfall was in may of this year. So this is bringing much needed relief. But because the ground is so dry, any amount of rain will really destabilize the ground across that area leaving the potential for the mudslides. People need to be very well aware that the potential for mudslides does exist for that region. Hes move on to some different weather. Were talking about a major cooldown across the upper midwest and its created quite a phenomenon on the lake shore drive near chicago in the great lakes. Lets get to some visuals before we explain why this happened. Well the gales of november came a day early. This is halloween and Lake Michigans waves reached a near record height of 22 feet on friday. Previous record was 22. 9 feet set back in september of 2011. Measured wind gusts of 59 miles per hour. This was the scene. Were talking about scenic lake shore drive being flooded leading to lane closures, traffic being backed up and even causing authorities to close the east end of chicagos famed navy pier. The cold front moved through and it changed the winds out of the north. Now this wind was actually running parallel with the entire length of Lake Michigan. This is called the fetch. And when you combine that with above average lake levels, were talking about lake levels that are at its highest since the 1990s and that strong northwesterly wind, that impacts the southern portions of Lake Michigan bringing waves upward of 22 feet with the buoy in the southern portions of Lake Michigan. And this should continue, we have a potential for pretty hefty waves across that region. Authorities are warning any residents to stay away from piers near the shoreline. With the passage of the cold front, meaning that the temperatures take a nose drive. Weve got freeze warnings for most of the Central United states. A snowstorm taking place near the southern appalachians. We could see a foot of snow before its all said and done. Very cold weather moving along the east coast. Back to you. Its coming.
