Tropical Storm Bill (2015)

The second named storm of the season, Bill developed from a broad area of low pressure over the northwestern Gulf of Mexico on June 16.

Heavy rains fell across parts of the Yucatán Peninsula, with accumulations peaking at 13 in (330 mm) in Cancún, the highest daily total seen in the city in nearly two years.

[1] The National Hurricane Center (NHC) first noted the potential of the formation of a tropical cyclone in the Gulf of Mexico during the mid-afternoon hours of June 12.

At the time, an upper-level trough was producing disorganized showers and thunderstorms over the northwestern Caribbean Sea, Belize, and the Yucatán Peninsula.

[2] Moving northwestward, the system tracked over the Yucatán Peninsula, and development chances increased as forecasts showed a more favorable environment within the Gulf of Mexico.

[3] Early on June 14, the trough began to interact with an upper-level low over the Gulf of Mexico, producing additional showers over portions of Central America.

[4] Later that day, Hurricane Hunters aircraft reconnaissance began investigating the system, and discovered an ill-defined but intact and broad low-pressure area over the south-central Gulf of Mexico.

[7] However, meteorologists Jeff Masters and Bob Henson of Weather Underground noted the possibility of Bill strengthening over land via the brown ocean effect due to floods in the previous month that helped saturate soils in Texas and Oklahoma.

[9] At 15:00 UTC on June 16, Bill reached its peak intensity with maximum sustained winds of 60 mph (95 km/h) and a minimum barometric pressure of 997 mbar (hPa; 29.44 inHg) as the storm was located 15 mi (20 km) south of Port O'Connor, Texas.

[10] At peak intensity, Bill made landfall on Matagorda Island at 16:45 UTC and began moving into inland Texas.

[1] The precursor to Bill and Hurricane Carlos in the eastern Pacific Ocean produced widespread heavy rain in Central America.

[15] Heavy rains fell across parts of the Yucatán Peninsula, with accumulations peaking at 13 in (330 mm) in Cancún, the highest daily total seen in the city in nearly two years.

A voluntary evacuation order was issued by the Galveston County Office of Emergency Management for people living on the Bolivar Peninsula.

In Brazoria County, storm surge caused minor coastal flooding at San Luis Pass Park, Surfside Beach, and Treasure Island.

In Harris County, minor storm surge and freshwater flooding was reported in Shoreacres, with the Taylor Bayou exceeding its banks.

[25] After between 4 and 8 inches (100 and 200 mm) of rain fell in Carter County, the local National Weather Service office issued a flash flood emergency for the area.

[28] In Indiana, the remnants of Bill contributed to the rainiest June on record in portions of the state, while Fort Wayne observed its wettest month ever.

[30] Near Troy, the remnants of Bill spawned an EF-0 tornado, which damaged trees in an area of approximately 0.33 mi (0.53 km) in length and about 140 yd (130 m) in width.

[36] A tornado spawned in Bartlett knocked down tree limbs, damaged the roof of a home, and carried a boat through the neighborhood.

[37] The remnants of Bill dropped 2.86 in (73 mm) of rain in Henderson, Kentucky, where the 25th annual W. C. Handy Blues & Barbecue Festival was being hosted.

[38] In West Virginia, the remnants of Bill brought flash flooding and downed trees, one of which fell on a car in Marion County.

Winds mainly knocked down power lines, trees, and branches in eastern Virginia, resulting in numerous road closures and damaging a shed in Sussex and several cars in Powhatan and Richmond.
