How does Isaias compare to other storms to hit the DC region?

Tropical Storm Isaias barreled up the coast Tuesday, bringing damaging winds and buckets of rain that flooded some D.C.-area roadways.

But how does Isaias stack up to other tropical disturbances that have hit the D.C. region?

For one thing, Isaias is far from the worst storm to impact the region, but it does share something with those other more powerful storms: a common first letter.

The D.C. region seems to attract “I-named” storms.

For example, the last hurricane to directly impact the region was Irene in 2011. The storm made landfall on Aug. 27, 2011, near Cape Lookout, North Carolina, as a Category 1 storm and brought heavy rainfall to the region — up to 11.5 inches in some areas in Southern Maryland.

In 2004, the remnants of Hurricane Ivan spawned several tornadoes in Maryland and Virginia — the largest outbreak ever in Virginia.

The year before that, in 2003, Hurricane Isabel brought tropical storm force wind gusts and surge flooding. Then-Virginia Gov. Mark Warner called it “probably the worst storm in a generation.”

Isabel was the deadliest, costliest and most intense hurricane in that Atlantic hurricane season, according to meteorologist Chris Strong with the National Weather Service in Sterling, Virginia.

“It’s a very devastating track for storms coming at us directly rather than something that’s coming more up the coast,” he said. “And Isabel was just massive amounts of tidal flooding and trees down, knocking power out to many, many people.”

However, earlier storms packed even more powerful punches to the region.

Another storm that was the worst to hit the region in terms of the powerful winds was in 1954: Hurricane Hazel brought wind gusts of 98 mph and set a record that has yet to be broken.

Back-to-back Hurricanes Connie and Diane in 1955, as well as Agnes in 1972, were just as destructive — but through major flooding instead of high winds. Agnes dumped more than 12 inches of rain in a short amount of time, washing away homes and roads, and killing 13 people in Virginia and 19 people in Maryland.

Hot, humid week ahead for DC area with severe storm risk

A dangerous heat wave will grip the D.C. area through Thursday, with highs in the mid to upper 90s and heat index values between 100 and 105. Hot and humid conditions are expected through Thursday, according to the National Weather Service, which said to expect daily thunderstorm chances and a risk of severe thunderstorms. 7News Meteorologist Eileen Whelan told WTOP that most of Tuesday will stay dry, but a few late-day thunderstorms are possible, especially north and east of D.C. as storms drift south from Pennsylvania. Any storm could produce damaging wind gusts and hail, but Whelan reiterated "storm chances are low" on Tuesday. Due to a lack of air conditioning, Parkdale High School in Riverdale, Maryland, closed early at 10:30 a.m. on Tuesday, Prince George's County Public Schools said in a social media post.
