Is Ana.

Tropical Depression TD05F intensified into a category 1 system and named Tropical Cyclone(TC)
Ana early this morning. TC Ana continues to move closer towards Fiji and was located about
175km northwest of Viwa at 9am today. The system is expected to slow down as it moves over the
group.
In its anticipated track, the eye of TC Ana is expected to be located closer to the Yasawa Group
tonight and approach Viti Levu early tomorrow whilst remaining as a category 1 cyclone.
TC Ana is likely to make landfall over Ra Province around tomorrow morning then continue to
move southeastwards over Viti Levu and track close to Kadavu around tomorrow night to Monday
morning. Please be advised that damaging winds are likely to begin several hours before the
cyclone centre passes overhead or nearby.
Gale force winds has been reported over Yasawa-i-Rara this morning and is expected to affect the
rest of the Fiji Group from later today.
Damages to weak structures and houses of very light materials is expected. It may also cause
disruption of electrical power distribution and communication services. Damages to crops and
vegetation with trees tilting due to very strong winds is also likely.
Heavy rain is expected to continue and become more frequent as TC Ana draws closer to Fiji. This
will cause flooding of roads, villages, towns and communities near streams, rivers and low lying
areas. Due to continuous rain in the last few days causing soil in the ground to become moist and
loose, this poses risk of landslides. Therefore, all communities living in flood and landslide prone
areas need to remain alert and take precautions when necessary.
Members of the public are advised to keep away from flooded drains, streams and rivers whilst
motorists are also requested to take extreme care when driving as there is risk of poor visibility in
areas of heavy rain and thunderstorms.
Moderate swells and breaking waves reaching the coastal areas may cause possible coastal
inundation and sea flooding especially during high tide. Sea conditions are too dangerous for sea
travel, sailing and other sea activities.
The current situation is closely monitored. Members of the public are advised to remain updated
with the latest weather information and adhere to authorities on the ground.

It is rapidly intensifying. Those storms get their act together faster than storms in the atlantic. I suppose due to a stronger coriolis effect.

Before I noticed it was the SPAC I wondered if I was somehow missing the Atlantic's first storm.

Well, for a split second anyway.
