Fall Tornadoes in Oklahoma
Since 1950, Oklahoma has had 373 tornado touchdowns in the months of September, October, November, and December. Most of these occurred in September and October. This is why we have what we refer to as our second severe weather season. It occurs every fall, usually beginning around mid-September.
Some Fall severe weather seasons are fairly quiet, while others can be quite active. There can be some correlation between an active 2nd season and an El Nino’ or La Nina’. Almost everyone has heard of our weather patterns being influenced by the Pacific Ocean temperatures near the equator. Based on what the temperatures are, it is either an El Nino’ or a La Nina’.
At the time of this writing (July 2015), we happen to be in a strong El Nino’ pattern, which is probably why we have had one of the wettest years in history in terms of rainfall. This El Nino is predicted to continue through the winter, which could mean we have above normal precipitation this fall and winter.
So, lets get back to the subject of severe weather, tornadoes, and our 2nd season. I have prepared a chart to help illustrate the apparent correlation between the number of tornadoes and the type and strength of the weather pattern occurring at that time.
YEAR | # OF TORNADOES | EL NINO’ STRENGTH | LA NINA’ STRENGTH |
OCT. NOV. DEC. | |||
1958 | 16 | WEAK | |
1970 | 17 | MODERATE | |
1982 | 8 | VERY STRONG | |
1986 | 13 | MODERATE | |
1992 | 17 | MODERATE | |
1998 | 34 | VERY STRONG | |
2001 | 19 | WEAK | |
2011 | 11 | STRONG |
Some notable months are as follows:
September 1992 16 tornadoes
September 1997 9 tornadoes
October 1998 27 tornadoes
October 2001 19 tornadoes
November 2011 11 tornadoes
Bottom line is, all it takes is the right kind of conditions and you can experience tornadoes anytime of the year. In the spring, severe weather occurs because of a battle between winter and summer. In the fall, severe weather occurs because of a battle between summer and winter.
Are you prepared? Do you own a storm shelter? If not, now is a good time to purchase one and have it installed. In February every year, many people start thinking about it again and then finally begin to inquire about a shelter in March in hopes of being prepared for the spring tornado season. By that time, hundreds of other people have already placed their order ahead of them. Now you find yourself at the bottom of a waiting list, not sure if you will even have it installed before the season winds down.
Enid Storm Shelters still has financing available through Communication Federal Credit Union at an interest rate of only 0.75%. That is an incredibly low rate. We do not know how long this rate will be available. If you are thinking about financing your storm shelter, take advantage of this low rate before it is gone.
Our 2nd season is almost upon us. Prepare today and be ready for it. You will then be prepared for the Spring 2016 tornado season. Think about it. What peace of mind knowing your family is safe from severe weather.
