A brief reminder that our Detailed Forecast coverage area tends to just be southern Mississippi — with a few parishes in southeastern Louisiana. This “heat map” of our coverage area is a good gauge to know if we are talking about your area.
I’ve had a chance to look some of the midday data over and I wanted to update the timeline for the county-by-county breakdown as well as a quick update on how things are looking for a forecast perspective.
Looking at some of the hourly forecast data, here is a quick map about how ‘good’ I’m feeling about the amount of precipitation:
I think some of the northern counties are getting pretty locked in for a 0.10″ (or slightly more) icing event. That isn’t enough to cause widespread problems, but it is enough to cause local issues – include power outages and icy roads.
A bulk of the area is still in the “battle zone” betweent he drier colder air and the moisture.
Farther south, we are starting to feel more certain about the lack of much meaningful icy potential.
I’ll continue to monitor the data as it comes in, but based on teh latest data, I have updated the timeline and threats for later tonight and through tomorrow morning. That update is below.
WINTERIZING TIPS
Hopefully you took some time this weekend to winterize your home, car, and life. If not, here are some tips from the NWS:
- Prepare your family
- Make a Family Communications Plan. Your family may not be together when disaster strikes, so it is important to know how you will contact one another, how you will get back together and what you will do in case of an emergency.
- Make an emergency kit for at least three days of self-sufficiency.
- Keep space heater safety in mind: Use electric space heaters with automatic shut-off switches and non-glowing elements. Remember to keep all heat sources at least three feet away from furniture and drapes.
- Prepare your home:
- Make sure your home is well insulated and that you have weather stripping around your doors and window sills to keep the warm air inside.
- Make sure you have a working carbon monoxide detector.
- Keep fire extinguishers on hand, and make sure everyone in your house knows how to use them. House fires pose an additional risk, as more people turn to alternate heating sources without taking the necessary safety precautions.
- Learn how to shut off water valves (in case a pipe bursts).
- Insulate your home by installing storm windows or covering windows with plastic from the inside to keep cold air out.
- If you have a wood burning fireplace, consider storing wood to keep you warm if winter weather knocks out your heat. Also, make sure you have your chimney cleaned and inspected every year.
- Have at least one of the following heat sources in case the power goes out:
- Extra blankets, sleeping bags and warm winter coats
- Fireplace or wood-burning stove with plenty of dry firewood, or a gas log fireplace
- Prepare your vehicle:
- Fully winterize your vehicle: Have a mechanic check antifreeze, brakes, heater and defroster, tires, and windshield wipers to ensure they are in good shape. Keep your gas tank at least half full.
- Keep an extra emergency kit specifically created for your car. In addition to the basic essentials, consider adding a portable cell phone charger, ice scraper, extra blanket, sand for traction and jumper cables.
- Rock salt or more environmentally safe products to melt ice on walkways. Visit the Environmental Protection Agency for a complete list of recommended products.
- Sand to improve traction.
- Other tidbits
- Make sure you have a cell phone with an emergency charging option (car, solar, hand crank, etc.) in case of a power failure.
- People who depend on electricity to operate medical equipment should have alternate arrangements in place in case power is out for an extended period of time.
- Plan to check on elderly/disabled relatives and neighbors.
- Plan to bring pets inside.
- Know where the manual release lever of your electric garage door opener is located and how to operate it in case you lose power.
- Fill a gallon container with water and place them in the freezer to help keep food cold.
- A NOAA Weather Radio broadcasts alerts and warnings directly from the NWS for all hazards. You may also sign up in advance to receive notifications from your local emergency services.
The cold Tuesday night and into Wednesday morning will likely be cold enough that some folks will need to drip faucets and open cupboards under the sink to make certain that pipes don’t burst.
TRAVEL
If you have to get out and drive tomorrow, please consult the county-by-county forecast to see when the liquid precip will change over to icy precip. But on top of that, know that…
MOST AREAS – Icy spots in low-lying areas, minor impacts to travel with slick roads and ice on bridges and overpasses likely for up to 6 hours
MANY PLACES – Icy spots on less-traveled roads with icy bridges and overpasses for up to 9 hours
SOME SPOTS – Freezing rain accumulated on surfaces with icy roads for up to 12 hours
FEW LOCATIONS – Impassable due to icy roads
This isn’t going to be an “everywhere” problem, but it may be a problem for you, so please drive carefully if you have to be out and about.
COUNTY-BY-COUNTY BREAKDOWN
For certain events I will try to cover as many counties as possible but please know that it takes a LOT of time to put these together. If I don’t cover your county it isn’t because I don’t care, but rather because there are only so many hours in the day.
So… Let’s take a look!
