Tropical weather and Montana don't typically belong in the same sentence, but you may want to pay attention to the upcoming hurricane season, which peaks in the middle of September.
Hurricanes may not directly impact Montana with wind and rain, but your wallet could feel the pain as the effects of a tropical system ripple across the nation. With so many oil and gas pipelines and refineries in the Gulf of Mexico, the entire nation's economy could feel pressure from tropical storm damage.
Since 2005, a number of hurricanes have come through the Gulf of Mexico, which is a major oil and gas hub for the entire nation. In 2005, the infamous Hurricane Katrina made a path through the gulf and caused some major destruction. The coastline from Texas to Alabama is one of the most concentrated energy production areas in the county, and a direct hit to that area will cause gas prices to skyrocket.
The US Energy Information Administration has created a new interactive web site that keeps you informed of how tropical weather can impact the price at your local pump (http://www.eia.gov/special/disruptions/). By tracking the projected path of a hurricane and mapping it over oil and gas locations, you can see when prices could spike. Unfortunately, a big hit could be overdue.
So as funny as it sounds, make sure you prepare for hurricanes in Montana.
