RECORD RAINS: Tropical Storm Allison compared to Hurricane Harvey, by the numbers

Friday, June 8, 2018
HOUSTON, Texas (KTRK) -- Intense rains from Tropical Storm Allison bombarded Houston on this night 17 years ago. In fact, so much rain fell in such a short period of time that Allison still claims some records over Hurricane Harvey.

Over 28 inches of rain fell just northeast of downtown Houston in a 12-hour span, far surpassing the nearly 21 inches of rain that fell over 12 hours during Harvey.

Allison's rains were more localized, unlike Harvey, which dropped nearly three feet of rain across all of Harris County over a four-day span.
