TWO tropical depressions are affecting the Fiji Group, says the Fiji Meteorological Service.
A senior weather forecaster at the Nadi weather office said TD 14F was centred over the Western Division yesterday morning and appeared to be moving slowly eastwards while a second depression christened TD15F lay to the north of Viti Levu.
He said TD15, situated 50 kilometres north of Nadi at about midday yesterday, raised concern because of the associated rainfall it brought with it.
"It is slow moving and expected to move between Viti Levu and the Mamanuca Group later this week before moving northwards and intensifying by this weekend," he said.
"We are concerned about the amount of rain this system could bring and there is still an opportunity for it to develop into a tropical cyclone as it tracks away from the group.
"We do not anticipate gale force winds but the real worry is that the associated rain could lead to flooding in low-lying areas."
The weather office issued a flood alert at 2pm yesterday for low-lying areas downstream of the Nayavu station in the flood-prone Wainibuka district but cancelled it by 7pm.
TD15F was reported to be moving east-northeast at 5kmph.
