Heavy Rainfall Causes Flash Flooding, More Rain on the Way

weather

DES MOINES, Iowa — Extremely heavy rainfall will continue to drench Central Iowa and the Metro this afternoon. Slow moving thunderstorms have been hammering Dallas and Western Polk county all morning and afternoon with more scattered storms expected into the evening.

While the storms will remain scattered, and the heaviest rain fairly isolated…the slow moving nature of the storms will lead to extreme flash flooding in local areas, and dangerously rapid rises especially on creeks and streams downstream of the heaviest rain. Flash flooding will be a major concern on these secondary waterways even in areas that may not receive much rain directly.

Thunderstorms are possible through the overnight, but should gradually diminish heading into Friday. While the afternoon should be mainly dry, better chances for more widespread heavy rain return on Saturday, with more storms and even severe weather possible into Sunday which will extend the flooding and flash flooding threat into early next week.

Totals through early afternoon:

Montezuma 4.70″

Waukee 4.65″

Windsor Heights 3.20″

Johnston 3.03″

Clive 4.5”
