Sufferers of hayfever and asthma are being warned of potentially dangerous conditions on the horizon.
Strong winds carrying dust across the region holds the likelihood of setting off a respiratory attack.
Thunderstorms are expected in Wagga towards the mid-morning into early afternoon, which could promote further perilous conditions for many who suffer breathing difficulties.
Springtime thunderstorms in the Riverina have been known to trigger episodes of storm asthma, reminiscent of the 2016 thunderstorm asthma event in Melbourne that killed 10 people.
High-risk sufferers have been warned to remain inside today, with doors and windows closed.
If venturing outdoors, make sure to be carrying medically-approved asthma medication.
Medical professionals have asked that attendees of today's Ag Races at the Turf Club keep a close eye out for friends who may be susceptible to the effects of respiratory attack, and seek immediate medical attention should issue arise.
Meanwhile, Transport for NSW has issued a warning to motorists to be weary of conditions on the roads today.
Reduced visibility may cause difficult driving conditions with severe dust and windy conditions sweeping through western NSW.
The Newell Highway has been particularly effected, along with the Mitchell, Barrier and Oxley further west.
"Road users experiencing poor visibility due to the storms are advised to reduce speed, turn air conditioning to recirculate, and be prepared to pull off the road and wait until conditions have improved," the NSW Transport statement has said.
