Keep umbrellas handy; Rain and flooding likely to continue

WEST LAFAYETTE, Ind. — Hoosiers should keep their umbrellas and flashlights handy because the thunderstorms that have marked spring, especially early June, likely will continue until the end of July.

Infrared satellite images of southern Indiana show widespread flooding of the White and Wabash rivers. The image on the left was taken on May 28, before the record rainfall, and the image on the right was taken on June 10. The images have a resolution of approximately 275 yards (250 meters). Purdue University’s Terrestrial Observatory captured the images from NASA’s MODIS-Aqua satellite.

La Niña’s control of the weather pattern will continue to make Indiana’s normally severe storm season more intense and generate storms more frequently than average, said Dev Niyogi, state climatologist and an assistant professor of agronomy and earth and atmospheric sciences at Purdue University. La Niña is a name given to the interaction of the atmosphere with cooler than normal sea surface temperatures in the tropical Pacific. This impacts global weather patterns.

“Whenever we are in a La Niña pattern, there is increased propensity for severe weather over Indiana during spring and summer with increased likelihood for thunderstorms and rain,” Niyogi said. “We are nearing the end of the La Niña cycle, which started last year, but the sea surface temperatures are still about one-half a degree cooler than normal.”

The cool ocean surface temperature and recent precipitation deluge tell climatologists that La Niña still has some punches to throw, he said.

La Niña could be the major reason for the weather pattern responsible for 9.85 inches of rain in Gosport in Morgan County on June 7. Edinburgh, Ind., has the rainfall record for the week of June 2-8 with 17.94 inches and also for a single day with 9.95 inches on June 8. According to the National Weather Service, precipitation of this magnitude is considered a 1-in-1,000 year event.

Although the current La Niña is coming to an end, Niyogi said that it’s likely the weather will continue to be wet all summer. But it’s difficult to predict amounts of rain or exactly where it will fall, he said.

“Rainfall is one of the most complex factors in nature,” Niyogi said. “The ground temperature, whether the ground is too wet or too dry, the altitude, the air temperature and humidity all interact to determine where precipitation will fall.”

Many of those factors came together over the southern third of the state during the first two weeks of June, he said. The effect was that a weather pattern of thunderstorms with heavy rain formed over that large area of Indiana and caused flooding. So much rain on already saturated ground, left water with nowhere to go except into homes, businesses and fields that quickly took on the appearance of new swimming pools and lakes.

“It’s difficult to say why some areas were hit with widespread heavy precipitation,” he said. “We’re still studying why some places receive heavy precipitation and others don’t. But we do know that people in Indiana should be prepared for more flooding.”

Second annual Operation Medicine Cabinet protects public, Wabash

LAFAYETTE, Ind. — For the second year, residents can safely dispose of their expired or unwanted prescription and over-the-counter medications through “Operation Medicine Cabinet.” Event sponsor Home Instead Senior Care in Lafayette is partnering with the Tippecanoe County Sheriff’s Office, Rosewalk Commons, and the West Lafayette Go Greener Commission for the one-day event that allows the public to safely dispose of expired or unwanted drugs.

“Operation Medicine Cabinet is a valuable community service that educates the public on how proper disposal not only protects loved ones from accidental ingestion but also helps protect the environment,” said Chris Irons, owner of the Lafayette Home Instead Senior Care.

Many residents flush their medications down the toilet or down a drain, he said. “But Indiana’s wastewater treatment system is not designed to remove these types of contaminants from the water supply.”

“In addition, pets and children can access medications that are carelessly thrown away in the trash,” said Irons. “Proper disposal also prevents illegal use of the drugs or theft of identity from prescription labels.”

Operation Medicine Cabinet will be held in two locations on Saturday, June 28, from 10 a.m. to 2 p.m. at Rosewalk Commons senior community, 250 Shenandoah Drive, in Lafayette, and in the Cumberland Park farmers’ market parking lot in West Lafayette. Collection will be supervised by the Tippecanoe County Sheriff’s Department and properly incinerated by the animal crematory at Hippensteel Funeral Home.
