(Updated to include Lenox Snow Ordinance)

With the chance of a significant snowfall to occur in southwest Iowa the Clarinda Police Department would like to remind the citizens of Clarinda about the emergency snow ordinance.  Chief Keith Brothers says the ordinance states that no person shall park any motor vehicle or other apparatus upon any street of the city that will obstruct the removal of snow when there has been an accumulation of two (2) inches or more. Any vehicle left parked on any street in violation of this ordinance may be impounded and subject to a traffic citation.

And, the Lenox Police Department reports The City of Lenox snow ordinance will be in effect beginning at 6-PM Wednesday. The ordinance will remain in effect until snow plowing operations have ceased. During snow removal operations, there is NO on street parking permitted. Vehicles in violation of the ordinance will be issued a $20.00 citation and may be subject to tow.

With the anticipation of a busy holiday travel weekend approaching, the Iowa Department of Transportation is cautioning drivers that the first major winter storm of the season may hamper some travel plans. The storm’s severity will vary depending on location. The National Weather Service is predicting 5 to 8 inches of snow along a line from Atlantic through Boone to Waterloo, with isolated instances of 10 inches possible. Rain is expected in southern Iowa along a line from Bedford to Oskaloosa. In between, a rain/snow mix is expected. All precipitation is expected to change to snow overnight Wednesday before ending Thursday morning.

Winds are expected to become very strong Wednesday night from the north/northwest. Sustained winds of 25 to 33 mph are expected, with gusts of 45 mph or more possible. The strongest winds are expected a few hours prior to daybreak through noon Thursday. Blizzard or near blizzard conditions may occur with visibilities reduced below one-quarter of a mile from time to time.

The Iowa DOT is offering several tips for safe winter travel during the impending storm. First, they say to ask yourself  “Is the trip necessary?” Often, delaying a trip by a few hours can give snow removal crews time to get the roads back to normal winter driving conditions. For traveler information, now available via the web, Twitter, Facebook or on your mobile phone, visit http://511ia.org/. Or simply call 511 (within Iowa) or 800-288-1047 (nationwide). Before you leave, let someone know your departure and expected arrival times, along with your intended route. Allow extra time to reach your destination.

Second, prepare your vehicle and passengers: Make sure your vehicle is in good mechanical condition and its gas tank is nearly full. Turn on your vehicle’s headlights so you can see and be seen. Ensure all passengers are wearing their seat belts or are in child safety seats.

Another tip, is be prepared to use your winter driving skills: Do not use cruise control. Allow extra stopping distance by maintaining adequate distance between your vehicle and the one ahead. Avoid abrupt steering maneuvers. Lower your vehicle’s speed, accelerate more slowly and apply the brakes in a controlled manner.

Carry an emergency survival kit and other supplies.Carry a mobile phone for making an emergency call, but  don’t use it while driving unless absolutely necessary. Your vehicle’s winter survival  kit should contain items to help sustain your life and the lives of your passengers should your vehicle become stranded. Those items can include: booster cables, candles and matches, a flashlight with fresh batteries, extra blankets and warm clothes, nonperishable food items, a can for melting water, and a snow shovel. Sufficient supplies should be in the kit for all persons traveling in the vehicle.

And remember: Use caution when approaching, following or passing a snowplow.  Remember the slogans, “Ice and Snow … Take it Slow” and “Don’t crowd the plow.”

OMAHA, Neb. (AP) — Residents across eastern Nebraska and western Iowa should prepare for the season’s first significant snow later this week, with weather forecasters calling for up to half a foot of snow and gusty winds. The National Weather Service says a large winter storm is expected to hit Nebraska midday Wednesday and move into Iowa by Wednesday afternoon.

Service meteorologist Van DeWald, based in Valley just east of Omaha, says heavy snow coupled with 15 to 30 mile per hour winds could make travel in those areas dangerous. DeWald says eastern Nebraska can expect several inches of snow, while western Iowa could see up to six inches of snow.

The National Weather Service in Des Moines says it seems like a lot of people are focusing only on the snow amounts with the storm system that is expected to hit Wednesday and Thursday. Officials say with the fresh snow pack, regardless of the amounts, wind gusts over 35 mph beginning early Thursday morning will create the potential for blizzard conditions throughout the day Thursday.

Be prepared for blizzard-like conditions Wednesday night and Thursday!

A Winter Storm Watch will be in effect beginning from Wednesday afternoon through Thursday afternoon for the KJAN listening area. The latest computer models show snowfall amounts will range from 5-to 8-inches across western Iowa, with some locations receiving up to 10-inches.

Of more concern to the Weather Service and Emergency Management Officials, is the winds. The Weather Service says winds will become very strong Wednesday nights from the north-to northwest, with sustained wind speeds of 20-to 30-miles per hour expected, along with occasional gusts to over 35. The strongest winds are expected at around daybreak, Thursday. Blizzard or near blizzard conditions are possible at that time, with visibilities reduced to less than one-quarter of a mile.

Very dangerous conditions are expected to develop Wednesday night into Thursday morning. Be prepared for very difficult travel and near blizzard conditions. Keep a weather radio handy, and if you plan on traveling, keep a winter weather survival kit in your vehicle. The weather service has a list of items you should keep in your kit, along with other tips on how to prepare and survive a Winter Storm in your home or vehicle, at http://www.crh.noaa.gov/dmx/?n=preparewintersafety.
