Firefighters and residents of the fire-stricken zone of Tasman district have been given no hope of help from rain today, but at least the winds are expected to be light.

Isolated showers in the afternoon and early evening are forecast for west of Tasman Bay, but that is 20km from the 1600ha zone in which fires, that exploded in Pigeon Valley near Wakefield on Tuesday, continue to burn.

"I know the fire service would like to hear there's a big band of rain coming over but unfortunately that's not the case," said MetService meteorologist Lisa Murray.

Civil Defence said the weather was favourable yesterday, the Pigeon Valley fire had not grown, and the intensity of the fire had decreased. However, the situation was vulnerable to changes in the weather.

The temperature today is expected to reach 22C, with a fine start and a partly cloudy sky from late morning.


Tomorrow is forecast to be another fine day in the tinder-dry Nelson/Tasman region, with showers confined to the mountain ranges, northerly breezes and a high of 25C.

The north wind is expected to pick up for a time on Sunday, with the temperature reaching 24C.

Rain is anticipated in the southern and central West Coast from a front that will move up the South Island overnight on Sunday/Monday. But based on the summer pattern in force since early last month, the front is expected to fizzle by the time it reaches Nelson/Tasman.
