Getting Your Car Ready For Winter Weather


When the leaves are empty of all their beautiful leaves and the winter winds start howling, you know colder temperatures are on the way. Almost by instinct, you get out the warmer clothes. You turn up the heat a notch and prepare for the long winter ahead. But your body isn't the only thing that is affected when winter comes knocking at your door. Our cars are also affected by changes in the weather - especially winter. So before jack-frost makes an appearance, it's time to winterize your vehicle.
Change your oil. The oil in your car changes depending on how it is running. During the winter months when it's cold, your engine needs thinner oil to run. Try using 5W-30 if you use regularly use 10W-30. But before you do anything, check with the manufacturer or read the manual. And for heaven's sake, make sure you change the oil regularly.
Winter usually means snow. And when driving on snow, you need good tires. First and foremost, make sure your tires are inflated to the proper weight. Then check the tread. See how much you have. If it's time for new tires, get them before rather than after. You'll need them driving in the snow. Another option is changing from regular tires to snow tires. If you decide to do this, change all four. Don't just change the front two or you are asking for a host of traction problems.
Did you know that the coolant in your car does more than one job? Of course, it cools down your engine. But it also acts to protect your engine from corrosion. It's good to use a coolant that has ethylene glycol in it during the winter months. The ration should be sixty percent coolant and forty percent water. If you have questions about this, check with the person who changes your oil. Remember, you are protecting an investment. The engine is the most expensive part to replace.
There are other little things that will make driving in winter more enjoyable. Make sure you have good rubber floor mats. Check for the ice scraper. Make sure it's not in the garage. Fill up your windshield washer fluid. You'll be glad you did when all the snow is flipping on your windshield from the semi-truck in front of you. Put a blanket in your car. It's good to have it there in case of emergencies.

100-Year Floods

 
The use of the term 100-year flood is really a statistical way of saying a flood is rare. Many people will talk of 50-year floods, 500-year floods, and 10-year floods. Each flood type is actually a way to discuss the chances of a flood happening in the same region. In other words, a 100 year flood does not happen once in 100 years. Instead, a 100 year flood has a 1 in 100 or 1% chance of occurring in any particular year. A 500-year flood only has a .2% chance of occurring in any given year. Flooding determinations and probabilities are based on recurrence intervals. The United States Geological Survey (USGS) defines a recurrence interval as the average number of years between floods of a certain size. In other words, how long is the average return period of a flood to the same region?
The National Flood Insurance Program (NFIP) also uses recurrence levels to determine whether a home owner should have flood insurance. The 100-year flood (1% chance of returning) is the standard used for floodplain management and to determine the need for flood insurance. For example, a structure located within a special flood hazard area shown on an NFIP map has a 26 percent chance of suffering flood damage during the term of a 30 year mortgage.

Weather Statistics

In meteorology, a chance is basically a common way to explain a statistic to people in a forecast. For example, a chance of rain has a statistical analysis associated with it. Because meteorology data is constantly collected and recorded, the chances of a flood happening in a region can also change over time. The actual number of years between floods of any given size varies a lot because of naturally changing climate conditions. Increased urbanization in a region will also factor into the chances of a major flood striking an area. In the case of flooding, the probability of a flood happening again are listed in the table below.

Factor Affecting Flood Recurrence Intervals

Other factors can increase or decrease the probability of a flood occurring in a given region twice in a row. For instance, if the ground is saturated, the chances of a river cresting and causing extensive flooding are greater. Prolonged storms and torrential rains can also cause extensive flooding. If the meteorological conditions are right, a storm can hang over an area for an extended period. Statistically speaking this can happen any time. Meaning the chances of having two 100-year or 500-year floods in a row are highly unpredictable.
So, can a 500-year flood happen two times in a row? The answer is yes. The recurrence of a major flood in a region simply means that although the odds were against it, the floods can happen. Think of it this way, while your chances of winning the lottery may be 1 in several hundred million, there have been people who have won the lottery 2 or more times!

Flood Probabilities

Chances of a Major Flood in a Region
Return Period Chances
500-year 1 in 500 (0.2%)
100-year 1 in 100 (1%)
50-year 1 in 50 (2%)
25-year 1 in 25 (4%)
10-year 1 in 10 (10%)
5-year 1 in 5 (20%)
2-year 1 in 2 (50%)
