Heavy thunderstorms and strong winds, will stir dust and reduce horizontal visibility to less than 1,000 metres.
The National Centre of Metrology and Seismology (NCMS) said a heavy cloud cover is expected over the southern and eastern areas of the country.
The rains were accompanied by thunder and lightning.
Warning signs have been put up at necessary areas along the beach, and parents have been advised to keep an eye on their children at all times.
The NCMS is urging residents to be particularly careful while driving, especially in low-lying areas which might flood during rains.
Drivers are advised to leave extra space between vehicles.
