THE Nadi Weather Office says people should begin preparing for a possible cyclone towards the end of December or early January next year.
Principal scientific officer forecasting at the Fiji Meteorological Service Misaele Funaki said while the possibility of a cyclone developing was slim at the moment, it would not hurt for people to be prepared.
He added that the current weather conditions are slightly different from the climate that was experienced last year prior to the arrival of Tropical Cyclone Evan.
"We are tracking a pulse that is currently over the Indian Ocean and should this begin to enter our arena then there are elevated chances as the winds gradually turn westerly for some sort of weather activity," he said.
Mr Funaki said the same pulse was responsible for the development of severe Tropical Cyclone Bruce in the Indian Ocean off the Indonesian coast. TC Bruce has intensified to category 3 with winds of up to 120 kilometres per hour.
"Due to the unpredictable nature of these winds, people should be prepared and not wait until the last minute to secure buildings and stock up supplies and water."
Mr Funaki said the intense heat, thunderstorms and increased lightning activity in the afternoons was indicative of the amount of energy in the upper atmosphere that was being dispersed in the afternoons.
"Usually this type of buildup of energy can be broken down by a cyclone.
Afternoon showers are expected today, with the weather clearing by tomorrow.
