1) The fall season has already displayed a wide variety of weather that has impacted the nation, including heat waves in California and an early record snowfall in Minnesota. According to meteorologists, an Arctic blast that descends deep into the country this weekend, is likely to shatter cold temperature records from Idaho and Montana all the way south to parts of New Mexico, Oklahoma, and even a bit of Texas. Heavy snow is also forecast, with snowfall amounts of up to a foot or more from the eastern ridges of Washington beginning on Friday to northern New Mexico sometime on Monday, with Montana likely seeing the highest snowfall amounts.

2) Thousands have been forced to evacuate as extreme wildfire activity was sparked by high winds in Colorado. The East Troublesome Fire grew another 45,000 acres by mid-afternoon Thursday, prompting additional evacuations in Grand County, including Estes Park and surrounding areas. A map of all evacuation zones is available from Grand County. Roads were closed to inbound traffic, and outbound roadways quickly became clogged with cars as people fled the area that was being shrouded in wildfire smoke.

3) Although hurricane season officially ends on November 1, the National Hurricane Center (NHC) is monitoring another trough of low pressure over the western Caribbean Sea. The system, which has recently become much more organized, is producing thunderstorms near Jamaica, the Cayman Islands and Cuba. According to the NHC, the system is likely to develop into a tropical depression over the next several days and has a 60% chance of further development over the next five days as it moves northeastward.
We are monitoring a low pressure area near the Cayman Islands that has become better organized overnight. This system could become a tropical depression over the
next couple of days while the low moves slowly toward western Cuba this weekend. More: https://t.co/tW4KeFW0gB #95L pic.twitter.com/94fHGhsMpi

4) The Volunteer Fire Department of Glen Haven, Colorado, has demonstrated the critical importance of being a Firewise Community and how that has helped save homes amid the Cameron Peak Fire, but its resources have dwindled. The town has a small, volunteer fire department, who spent hours of mitigation work, training, and educating homeowners to make their homes fire-ignition resistant. About half of the 400 homes in the town were at risk from the wildfire, but according to local fire officials, the fire left standing those homes that had employed FireWise mitigation efforts, also known as defensible space.

5) Hurricane Epsilon has been downgraded to a Category 1 storm after rapid intensification into a major hurricane occurred on Wednesday as the storm approached Bermuda. Fluctuations in intensity are expected over the next day, but Epsilon is forecast to begin weakening sometime on Saturday as it moves off to the northeast. According to the National Hurricane Center (NHC), the storm is producing large swells that will affect Bermuda, the Bahamas, the Greater Antilles, and the Leeward Islands, along with the East Coast of the United States and Atlantic Canada over the next few days. The storm will potentially cause dangerous, life-threatening surf and rip currents.
6) The majority of Northern California remains under a Red Flag Warning until 5 p.m. Pacific Time on Friday, but the reprieve from the wind will be short-lived. A cold front is working its way into the area, and temperatures are expected to drop significantly over the weekend. A new front is set to move in beginning Sunday morning, which will bring another round of high winds and low humidity. The National Weather Service (NWS) has already issued a Fire Weather Watch for critical to extreme fire weather conditions, which are set to begin late Sunday morning, October 25, and continue through Tuesday afternoon, October 27, as another approaching weather front brings extremely strong winds and poor humidity levels.
After a bright, breezy Wednesday, MUCH stronger #wind arrives tonight through Thursday in northern #California. Red Flag Warnings, Freeze Warnings/Watches & Wind Advisories have been issued! I'll have your complete 7-day weather forecast on @ActionNewsNow at 4, 5, 6, 10 and 11pm! pic.twitter.com/RKbBhSqMI6

7) Due to current Red Flag Warnings, Pacific Gas & Electric (PG&E) implemented Public Safety Power Shutoffs (PSPS) beginning on Thursday, October 21. Power is expected to be restored to most locations between 2 p.m. and 8 p.m. Friday, but a new round of PSPS may begin again early Sunday morning, October 25, due to forecast extreme fire weather. According to the PSPS map, PG&E will post information regarding the new potential shutoffs by 8 p.m. on Friday, October 23.
PG&E says Public Safety Power Shutoffs are possible in the Bay Area from Sunday to Tuesday when dangerous winds are forecasted to pick up. https://t.co/E68agPBE81

8) The Association of American Railroads stated that in 2019, nearly 400,000 barrels of crude oil were transported around the country each day. Although the majority of those rail transports occur without incident, accidents do happen and local preparedness is critical to mitigating community and environmental impacts from incidents. A training program offering critical information on best practices is available from the Pipeline and Hazardous Materials Safety Administration (PHMSA). The training, Transportation Rail Incident Preparedness and Response (TRIPR) High Hazard Flammable Trains, offers a flexible approach to pre-incident planning and response for first responders and emergency services personnel. The training is meant to help them safely manage an incident response to train accidents involving Hazard Class 3 flammable liquids train cars.
According to data from the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) and the Federal Energy Regulatory Commission (FERC), 99.999% of crude oil, petroleum products and natural gas transported by pipelines reach their destinations safely. pic.twitter.com/yFHuUav7uw
