A Second Severe Weather Season

Severe weather outbreaks are synonymous with the spring season, but there is an ever-so-slight increase in activity in the fall as well. As the days grow shorter and the weather turns cold, the insurance industry needs to remain on guard, as this is the height of the second severe weather season.

Spring marks the shift from brutal cold to relentless heat, and the United States is often sharply divided between warm and humid weather in the south and cold and dry conditions to the north. The steep temperature gradient allows the jet stream to dip farther south, creating more opportunities for severe weather outbreaks to unfold.
As the country becomes uniformly and increasingly warmer in the summer, the relative lack of a temperature gradient usually pushes the jet stream far enough into Canada that it tends to only affect the northern part of the United States. This retreat of the jet stream allows the severe weather season to calm down – not completely, of course – but usually prevents the intense outbreaks of severe weather often experienced in April, May and June.

When fall rolls around and the country again starts to experience wild swings in temperature, the jet stream dips south once more and allows weather systems to develop and interact with the warmth and humidity. This results in spring-like severe weather outbreaks complete with a second spike in tornado activity, which is often accompanied by other types of severe weather.

The chart above shows monthly tornado reports between 2008 and 2017. To help illustrate this second season of severe weather, the overall monthly reports have been capped at a maximum value of 300. While total tornado activity varies widely from year to year, every spring produces a pronounced spike in tornado activity which is why we have capped the graph above at 300. This spring peak also provides the insurance industry with its primary season for severe weather loss. However, in each fall season between 2008 and 2017, highlighted in the red arrows, a clear secondary spike in tornado activity has occurred. While some of these fall twisters are a result of landfalling named tropical storms, most of the outbreaks are the consequence of the same processes we see during spring severe weather events.

Some of the fall tornadoes can be particularly strong. In 2013, several tornadoes impacted Illinois, including an EF-4 tornado that hit the small town of Washington. This round of severe weather caused almost $1B of loss to the insurance industry. This case was unusually rare as, typically, severe weather takes aim at the southeast, and the overall fall losses to the insurance industry are much smaller in total value.

Closing the Books on 2018 Severe Weather

Typically, by the end of October, 98% of the 10-year average annual insurance industry loss in the U.S. has developed. Similar to the trend in severe weather reports, there is a small, but noticeable, increase in secondary severe weather insured loss data for both the 10-year average annual loss and the number of events for the month of October.

The second season has been quite active this year, with several notable bursts of severe weather activity.

The most active tornado report day of 2018 (so far) was Halloween night, with 61 tornadoes occurring, breaking the previous record of 51 which occurred on April 13. Of course, an exceptionally quiet spring season likely helped to contribute to this unique scenario. What is also unusual is that, thus far, Property Claims Services has yet to issue a Catastrophe Bulletin for this outbreak from October 31 – November 2.

Below is a look at when severe weather associated with tornadoes happened this past year.

Here are the annual anomalies of 2018 tornado days to-date. Tornado alley, as it’s popularly defined geographically, is entirely below-average, but parts of Louisiana and most of the East Coast of the U.S. have been above-average.

In fact, almost as many tornadoes have occurred this year in New England (19) as in Oklahoma (22), which adds to the noteworthy severe weather year that has transpired. Preliminary data suggests the state of Connecticut has had nine tornadoes this year – the most on record. The tiny state of Rhode Island has had one tornado, which tied for the most to have ever occurred during a calendar year. In Pennsylvania, 31 tornadoes were reported, which is the highest annual number in 20 years.

The U.S. is currently in a major tornado drought. There has never been a year since 1950 that has passed without an EF-4 or EF-5 tornado occurring, but this scenario is appearing likely this year as, currently, the U.S. is in its longest stretch without a violent EF-4 tornado and closing in on the longest stint without a destructive EF-5 tornado.

Summary:

This year’s severe weather looks to be completely average when compared to the last 10 years in terms of insured loss, barring any major severe weather outbreak over the remaining 48 days in 2018. After a quiet spring, tornado activity has been playing catch-up during an active second season, with severe storm reports of wind following the 2005 – 2015 average count. However, hail reports, which are not as common in the second season and over the winter months, will likely end up being well below the 2005 -2015 average report count.

With the impending El Niño for the winter of 2018 – 2019, one should expect an active storm track across the southern states with greater-than-normal severe weather across the Southeast including Florida. Although we are already potentially seeing this pattern of severe weather, not all El Niños are the same. As details emerge, more insight will be provided on what to expect for the winter and spring severe weather seasons across the Southeast states which could be more active than normal.

BMS makes senior energy hire

BMS Wildfire Update Nov 9th

California’s typical wildfire season takes place in the fall, with the majority of large insured loss events occurring in October. Of the 27 large insured wildfire losses occurring in California since 1964, 16 have occurred in the months of October, November and December, and have accounted for 87% of the total losses over that time span. After an already long and destructive wildfire season for much of the western United States (which includes the Carr Fire and the Mendocino Fire Complex in California in July and August) that has resulted in over $1.3 billion of insured loss, major fires have again ignited in California on Thursday, November 8th. Much of the state is under an elevated fire risk, with almost 10,000 square miles under critical fire conditions according to the National Weather Service. Red flag warnings have also been issued, which represent conditions of very low humidity and high winds that tend to result in extreme fire behavior.

The cause of the Camp Fire has yet to be determined, but it started in the early hours of November 8 near the Plumas National Forest. The first firefighters to arrive found about 10-15 acres burning. Wind gusts of nearly 50 miles per hour helped accelerate its growth and spread it into the town of Paradise, CA.

BMS iVision has a direct feed of the current fire perimeters. These perimeters use the IRWIN (Integrated Reporting of Wildland-Fire Information) system. Perimeters are collected in the field by a variety of means, including infrared flights, and by using a GPS unit to map the perimeter. BMS clients can use these maps to see if any risks are exposed to the fires.

Initial reports suggest well over 2,000 residential and commercial structures have been destroyed by the fast moving fire which quickly spread embers into the center of town. The fire is currently encroaching on Chico, CA, and Highway 99 and several thousand other structures are still threatened by this fire. It should be noted that typically when fires burn over 1,000 structures, it’s safe to say that the insured loss will likely be above $1 billion.

Elsewhere across the state, the Hill and Woolsey fires ignited Thursday in southern California near the Thousand Oaks, CA community and began spreading rapidly. Evacuations have been issued this morning for the entire coastal community of Malibu, CA. Damage has been reported from the Hill fire, but the full magnitude is currently unknown. Just to the south, the Woolsey fire has jumped the 101 highway and has destroyed multiple structures according to Ventura County Fire Department. The Malibu area is under mandatory evacuation due to both of these fires, as authorities expect they could burn all the way to the coast and clearly there is major exposure in the current evacuation area.

In total, there are 13 known fires currently burning in California. With extreme fire conditions occurring, many of these fires will be difficult to contain and it is expected that several insured loss events could result from any of these fires. BMS iVision does have active wildfire layers, such as the current satellite derived hot spots and when issued, the integrated reporting of wildland fire information perimeters will be shown. Both of these resources allow the user to access the scenario based tools within iVision to understand the exposure and damage potential from these fires.
