HEAVY rain generated by a trough of low pressure is expected to cause flash floods in parts of the country.
The Nadi Weather Forecasting Centre said parts of Vanua Levu, the Lomaiviti Group and Kadavu experienced heavy rain yesterday afternoon.
Acting director of meteorology Aminiasi Tuidraki said a trough of low pressure was coming down towards the group over Vanua Levu.
Mr Tuidraki said those living in the Suva and Nausori areas would also experience heavy rain at times.
"There is also a low pressure to the far northwest of Fiji near Solomon Islands and it is sliding down towards the southwest of the country," he said.
"It will bring over associated clouds and rain. Right now, there is a lot of heavy rain from Udu Point to Nabouwalu on Vanua Levu.
"It is also raining in the Lomaiviti Group and Kadavu is also experiencing some rainfall.
"We have been experiencing rainfall for some time now and the soil is saturated. The heavy rain being experienced in places now will just come and spill over. There can be some flash floods.
"The trough coming over Vanua Levu will go across the group and the weather should ease a bit on Saturday.
"But the trough of low pressure sliding down from near Solomon Islands will result in rain again from next Monday or Tuesday."
Mr Tuidraki said the weather office would keep an eye on the trough of low pressure moving down from near Solomon Islands.
Meanwhile, police are asking people in the Western Division to take heed of weather warnings to avoid casualties.
West police spokeswoman Naina Ragigia said parents and guardians should take extra precaution for their children, especially during heavy downpour.
