The Meteorological Department has warned of heavy rains along the coast region.
The report from the weatherman indicated that the region will receive rainfall of more than 30mm in 24 hours from Wednesday to Friday.
The intensity of the rainfall is expected to increase on Saturday and Sunday.
The rains are likely to be accompanied by strong winds and may cause flooding in low lying areas near the coastline and other water sources.
Residents living in Kwale, Kilifi, Mombasa, Lamu, Taita Taveta and some parts of Tana River have been warned to be on the lookout for flash floods.
The residents have also been cautioned against driving, wading or walking through fast-moving rain water.
The heavy rains and strong winds may result in storm surges along the Coast, hence fishermen and those in the marine industry have also been put on high alert.
