What's the forecast for this one, SH? It's only a cat 1 at the moment, so I presume they're expecting it to intensify, but how much?

REMARKS:

Cyclone named at 01Z today due to ship observations and low level centre nearing deep convection. Westerly shear remains. With environment likely to gradually improve over the next 24 to 48 hours as high amplitude mid latitude trough moves east, slow development is forecast.

Ship observations of gale force winds within 100 km of the centre in last two hours still justify TC status. Namely:

PCKU: SE wind at 35 knots while at 17.7S 154.6E

HACHIUMA: easterly wind at 35 knots while at 18.2S 155.1E

Notes:

This product is issued every six hours; the Cyclone Advices (Watches and Warnings) are

usually issued more frequently and contain more useful information for coastal communities.
