AccuWeather’s Impact Indicator™ Once Again Delivers Unique Insights and Highlights Impact Areas Days in Advance of Blizzard



AccuWeather clients once again benefit from advanced lead time and highly detailed impact areas effectively showing the magnitude and scale of disruption.

The first major winter storm of the new year to plague the East Coast began as a southern system on January 3, 2018. Cities such as Charleston, SC, experienced blinding snows, frigid temperatures, and high winds, impacting travel and causing many people to stay inside. The winter weather expanded northward on January 4, 2018. As the storm strengthened over the Atlantic Ocean, heavy snow and gusty winds pummeled coastal portions of the Mid-Atlantic and into New England, forcing many businesses, schools, and government offices to close.

The winter storm walloped cities like Block Island, RI, and Portland, ME, where blizzard conditions were met. The National Weather Service defines a blizzard as a storm which contains large amounts of snow, or blowing snow with winds exceeding 35 mph and visibilities reduced to 1⁄4 mile for at least 3 hours.

The storm was captured by AccuWeather’s patented Impact Indicator™. The Impact Indicator combines historical weather data and property damage estimates into a unique algorithm that measures risk of various weather phenomena on a scale of 1 to 10. Weather events that happen frequently for a location and are not likely to cause significant damage have an impact level of 1. Weather events that rarely occur and cause the most damage have an impact level of 10.

Companies can use this proprietary index to plan and stay on top of the latest weather developments, to strategize to meet anticipated demand and be ahead of the competition, and to visualize data for more effective decision making. With the ability to be integrated with ERP, logistics, sales or supply chain systems, clients can more clearly understand how a particular weather event will impact their location.

For example, the Impact Indicator can help operations managers ensure employee safety and understand exactly how many workers, distribution centers, and stores that might be impacted by a weather event. Similarly, marketing personnel can use this information to increase performance and maximize profits from weather-related opportunities. 

On New Year’s Day, 3 days prior to the system unleashing snow and wind in the Northeast, AccuWeather’s Impact Indicator triggered several major metropolitan areas for impacts exceeding a level 8. Bangor and Caribou, ME, Providence, RI, Bethany Beach, DE, Worcester, MA, Ocean City, MD, Plymouth, NC, and Brick, NJ, were a few of the cities among the forecasted high impact zones.

In early October, AccuWeather accurately predicted chillier winter conditions this season, with above-normal snow and the coldest air of the season arriving in the Northeast and mid-Atlantic in January 2018. 

“All along, with AccuWeather we were ahead of the competition. We were on top of things with our constant adjustments to the snowfall map, plus we accurately predicted higher snow amounts earlier than most of the competition in the market.”Lee Goldberg, WABC-TV, ABC Affiliate in New York, New York

“Once again, AccuWeather lived up to its name by predicting how our region would be affected by this storm with Superior Accuracy, which in turn enabled WPVI to give our viewers the best and clearest idea of what to expect and how to stay safe.”Paul Trombello, WPVI-TV, ABC Affiliate in Philadelphia, Pa.
