Flash flood warning for parts of Cook, DuPage counties

Today could be a replay of yesterday with tropical humidity and daytime sea breezes giving way to locally heavy afternoon showers and even thundershowers. Rain and runoff may produce hazardous driving conditions. Land slides are possible in areas of steep terrain. The NSW reported 3.61 inches of rain in one location in the Charleston area. Weather radar and rain gages showed that the heavy rains have ended.

The National Weather Service also posted a flood advisory for Lanai until 4:45 p.m. Tuesday. These showers are almost stationary.

Parts of Oahu got hit with wet weather Tuesday. Areas impacted include southeast Oahu between Waimanalo and Kailua, and Windward Oahu from Kahuku to Waiahole, including Waikane stream.

Central Oahu saw some rain as well.

Emergency officials say they’re monitoring conditions closely. Flooding was also reported north of Octavia along Bone Creek and on some county roads.

At 2:40 p.m., radar showed that most of the heavy rain over Kauai was gradually weakening with a few pockets of heavy showers impacting southwestern Kauai. This warning may need to be extended if Flash Flooding persists.

A flash flood watch means the threat of flash flooding exists. Flash flooding is very unsafe.

Monitor the latest forecasts and be prepared to take immediate action if flash flood warnings are issued.
