The number of consecutive days of rainfall for Indianapolis is nearing the record high of 11 for the month of June, with six wet days in a row so far and several more potentially on the way.
Al Shipe, National Weather Service hydrologist in Indianapolis, said above normal levels of rain are expected to continue through June 28.
“That doesn’t necessarily mean it will rain every day,” Shipe said. “But there is no end to the rain in sight. There are certainly some areas pushing record rainfall.
The remnants of Tropical Storm Bill continued to soak the state on Friday.
“I don’t think there’s much of a dry spot in Indiana, and some areas have had more than 8 inches above the norm. This weather is typical for July and August but not for the month of June.”
He said 4 to 5 inches of rain in June is normal and Indianapolis already has received 5.1 inches of rain this month with still 11 days to go. Last year, as many as 7 inches of rain fell during June. The record high of 12 inches occurred in 1875.
Since Thursday Boone County has been affected by up to 3 inches of rain. Hamilton County was under a flood warning Friday evening through through Saturday and was making sandbags available to residents.
For most of this week the rain has focused on portions of Northern Indiana, which has resulted in some major flooding. The flooded St. Marys River was threatening about 80 homes, Adams County Emergency Management spokeswoman Melissa Norby told The Associated Press.
A flash flood watch covered much of Southern Indiana, where forecasters predict that 3 or more inches of new rain could fall through Sunday.
The climate on the east side of the United States is affected each year by the Bermuda High, which refers to the high pressure levels that form over the Atlantic Ocean near Bermuda every summer. Shipe said that these levels moved in a westerly direction earlier than normal this year.
“The cold fronts Indiana receives from Canada during June have also been stronger than those typically seen in July or August, which has caused greater rainfall,” Shipe said.
Due to Friday’s tropical disturbance, Indianapolis will be more likely to continue experiencing on and off light rain.
Weather Service climatologist Ken Scheeringa said the record for consecutive days of measurable rain in Central Indiana is 17 days. This occurred in 1968 between May 18 and June 3.
