A round of winter winter – likely with a large amount of snow and possibly with some ice – is expected over the next couple days. Experts remind people of simple steps to be ready for hazardous conditions.

The National Weather Service in Pleasant Hill says rain could start this late afternoon, is more likely this evening and is virtually certain for Friday – up to half an inch – with a Friday high of 42.

Then it gets cold and messy: Rain, snow, sleet and possibly freezing rain come Friday night. That could mean 1 to 2 inches of snow and sleet as well as a thin layer of ice. Friday’s overnight low is 20.

That wintry mix turns to snow after 5 a.m. Saturday, though some freezing rain could linger with the snow through 8 a.m. The snow continues through the day – heavy at times– and the metro area could get another 3 to 5 inches. The high is 27.

The snow ends by Saturday night, and then temperatures gradually rise. Saturday’s low is 14, followed by a high of 39 and a low of 24 Sunday, then 47/35 Monday.

Ready for the road

Officials usually advise people to stay off the roads in hazardous conditions. Even so, the Weather Service says, it’s a good idea to have your vehicle winterized and to carry a kit with:

• Mobile phone, charger, batteries.

• Shovel.

• Windshield scraper and brush.

• Battery booster cables.

• Blankets/sleeping bags

• Flashlight with extra batteries.

• First-aid kit.

• Knife.

• High-calorie, non-perishable food.

• Extra clothing to keep dry.

• Large empty can to use as emergency toilet, tissues, toilet paper and paper towels.

• Small can and waterproof matches to melt snow for drinking water.

• Sack of sand or cat litter for traction.

• Tool kit.

• Tow rope.

• Water container.

• Candle and matches to provide light and in an emergency, lifesaving heat.

• Compass and road maps. Don't depend on mobile devices with limited battery life.

Ready at home

The Weather Service advises having these things at home to ride out problems that arise with a winter storm, such as losing power:

• Flashlight and extra batteries.

• Battery-powered NOAA Weather Radio and portable radio.

• Extra food and water such as dried fruit, nuts, granola bars and other food requiring no cooking or refrigeration.

• Extra prescription medicine.

• Baby items such as diapers and formula.

• First-aid supplies.

• Heating fuel. Refuel before you are empty; fuel carriers may not reach you for days after a winter storm.

• Emergency heat source: fireplace, wood stove or space heater properly ventilated to prevent a fire

• Fire extinguisher, smoke alarm. Test smoke alarms monthly to ensure they work properly

• Extra pet food and warm shelter for pets

Also, review generator safety: Never run a generator in an enclosed space

Make sure your carbon monoxide detector is working correctly and that the outside vent is clear of leaves and debris. During or after the storm, make sure it is cleared of snow.

Home fires are common each winter when trying to stay warm. Review ways to keep your home and loved ones safe.
