AccuWeather First to Predict Life-Saving Impact Driven, Detailed Forecasts Ahead of Hurricane Maria AccuWeather provided clients and residents with 5-days of advanced notice for Category 4 Hurricane Maria, in San Juan, PR.

AccuWeather First to Predict Life-Saving Impact Driven, Detailed Forecasts Ahead of Hurricane MariaAccuWeather provided clients and residents with 5-days of advanced notice for Category 4 Hurricane Maria, in San Juan, PR.

During the morning of Wednesday, September 20, 2017, Hurricane

Maria made landfall near Yabucoa, Puerto Rico, as a Category 4

storm with maximum sustained winds of 155 mph. This made Maria

the first Category 4 hurricane to make landfall in Puerto Rico in

85 years, causing catastrophic damage and a major humanitarian

crisis in Puerto Rico.

While Maria brought 2 – 3 feet of rain to many locations

throughout the island accompanied by a strong storm surge that

caused extensive flooding, the greatest impacts were in the form

of damaging wind gusts in excess of 115 mph. Many observation

stations failed before the worst of Maria hit the area and therefore,

it is difficult to ascertain just how strong observed winds were

across the island.

Ahead of this event, AccuWeather and AccuWeather Enterprise

SolutionsTM expert meteorologists issued timely, impact-driven,

detailed forecasts to clients and the general public warning of

the severity of the event that would unfold. These forecasts with

Superior AccuracyTM were issued prior to that of any other

weather service providers.

Friday, September 15 In a high impact forecast briefing, ADC meteorologists warn

of the potential for the budding storm to bring impacts to the

Caribbean Islands, while the NHC update has no mention of

potential impacts to Puerto Rico and does not cover the island

in their cone. AccuWeather warnings from later that day include

“hurricane conditions” and damaging winds with a peak wind gust

of 122 mph (196 km/h).

Sunday, September 17 In an article posted on AccuWeather.com, the threat of mudslides,

flooding, power outages, and structural damage is deemed likely

across Puerto Rico, while clients were warned of specific impacts

they would endure.

Monday, September 18 In an updated article posted on AccuWeather.com, the threat

of power outages and structural damage continues to be

emphasized and prioritized to the front of the article. Another

briefing warns of a “catastrophic threat to lives, property and

the economy....” and mention that Maria is expected to have

sustained winds of 130 mph (209 km/h) or more upon landfall.

Other weather providers merely mentioned “damaging winds.”

These devastating wind gusts resulted in complete destruction

of the power grid, leaving 100% of the island without power as well

as running water or sewage. Additionally, thousands of homes and

businesses were destroyed and telecommunications throughout

the island “collapsed,” according to one Puerto Rican administrator.
