Central West residents prone to respiratory conditions and hay-fever are being advised to take extra precautions in the wake of thunderstorms alert in the state.
Weatherzone meteorologist Graeme Brittain said thunderstorms are currently moving towards the coastal areas.
“The chances of thunderstorms are low in the Central West, except at one or two places,” Mr Brittan said.
“The northern part of the Central West, mainly areas like Nyngan and Dubbo, can experience rain up to 60 millimetres.”
Rain is expected to range from 10 and 20 millimetres in the remaining areas on Wednesday, according to Weatherzone.
NSW Health director of environmental health, Richard Broome, said late spring saw high levels of pollen in the air and it could trigger asthma and respiratory conditions, especially during thunderstorms.
“Even if you don’t have asthma, you should take extra care because pollen is at its highest level now and may spark breathing difficulties in some people,” Mr Broome said.
“Thunderstorms cause pollen grains to explode and release fine particles which can be inhaled deeply into the lungs, causing even more people to wheeze and sneeze.”
NSW Health said anyone with diagnosed asthma should carry their medication at all times.
