PEOPLE have been urged to prepare now, take heed of warnings and act responsibly to avoid the unnecessary loss of lives and property.
The request was made by the Fiji Meteorological Service director Alipate Waqaicelua last night after a tropical depression was upgraded and named Tropical Cyclone Evan.
Tropical Depression 04F was upgraded and named as a tropical cyclone at 2:30pm yesterday.
Being Category 1, Tropical Cyclone Evan's centre was located about 300 kilometres west of Apia, Samoa at 3pm yesterday.
The tropical cyclone was moving towards the east at 20 kilometres per hour, was intensifying and may reach Category Two or storm force in the next 24 to 48 hours.
Mr Waqaicelua said on this track, the cyclone centre was expected to make landfall over Savaii, Samoa, last night before making a U-turn towards the south, over Samoa still, and head back towards the west later tomorrow.
"If Evan maintains its projected track and intensity trend after leaving Samoa, it should move across the northern parts of Tonga on Saturday and arrive into the Fiji waters by Sunday, December 16 at least as a Category Two," he said.
"Additionally, ahead of this cyclone, as it heads for Fiji, damaging heavy easterly swells are expected."
Mr Waqaicelua said these swells could cause sea flooding of low-lying coastal areas.
"All communities in Fiji should be prepared now, heed warnings and act responsibly to avoid unnecessary loss of lives and/or property," he said.
For a Category One cyclone, the 10 minute mean wind is at a speed of between 63 and 87 kilometres per hour.
The maximum three second gust for a Category One cyclone is less than 125 kilometres per hour, which is damaging wind.
For a Category Two cyclone, the 10 minute mean wind speed is between 88 and 117 kilometres per hour.
The maximum three second gust for a Category Two cyclone is between 125 and 169 kilometres per hour, which is destructive wind.
