Tips for Dealing with Heavy Rain

Heavy Rain and Flooding Warning: What to Know Today

Today's weather has brought significant rainfall and flooding concerns to parts of Indiana. An intense weather system has led to some of the worst flash flooding seen in recent years, particularly in the Indian Heights and Wildcat Creek areas. Reports indicate that heavy rain has caused roads to become impassable, trapping residents and disrupting travel just south of Kokomo.

According to the Indiana State Climate Office, radar estimates show that some areas received over 7 inches of rain. This surpasses historic flood events, with some neighborhoods experiencing flash floods not seen since July 4, 2003.

Boone County has also been hit hard, with a Flash Flood Warning issued after 3 to 8 inches of rain fell in a short period. The combination of a tropical-like air mass and a slow-moving upper-level low pressure system is fueling these heavy downpours. Many of these showers today produce rain rates exceeding 2 inches per hour — even without thunder, making them especially dangerous.

In fact, Gaston in Delaware County reported a staggering 6 inches of rain within just three hours this morning. As daytime heating continues and the weather system lingers, additional areas are likely to see very heavy rainfall through sunset tonight.

What to Expect for the Rest of Today

An axis of intense downpours has set up around the Indianapolis metro area, increasing the risk of flooding in the coming hours. The heaviest rain is focused along and south of the I-70 corridor, stretching into south-central Indiana.

Rainfall amounts will vary greatly—from just a quarter-inch in some spots to 2-4+ inches during short, intense storms reminiscent of Florida's downpours. Be cautious: do not attempt to drive through flooded roads. Remember, “Turn around, don't drown.”

Rain should decrease from north to south later this evening, with most activity wrapping up by midnight.

Possible Cold Air Funnels and Other Notes

Because of the tropical nature of the air and circulation around the upper low, brief “cold air” funnels may form today. These rare phenomena can be startling but typically do not reach the ground.

Looking Ahead: Father's Day and Beyond

Conditions are expected to improve by Sunday — Father's Day — with only spotty showers and less widespread rain. Temperatures will reach the low to mid-80s, accompanied by hazy sunshine as the upper system finally moves away.

Next week looks more active. As hotter air expands into the Ohio Valley, Indiana will be on the northern edge of a heat dome, increasing the chances for clusters of strong storms. Meteorologists will continue to monitor and update the timing and severity of these events.
