Thunderstorm asthma.

• Thunderstorm asthma is a form of asthma that is triggered by an uncommon combination of high pollen (usually during late spring to early summer) and a certain kind of thunderstorm.

• Anyone can be affected, even if you do not have a history of asthma.

• People at increased risk have a history of asthma, have unrecognised asthma, have hay fever (allergic rhinitis), (particularly seasonal hay fever), or are allergic to grass pollen.

• An asthma flare up can vary in severity and can be life-threatening. If there are signs that a person’s condition is deteriorating, urgent care should be sought.

• Be aware of forecast thunderstorms in the pollen season particularly on days with a HIGH or EXTREME pollen count. Where possible, stay indoors with doors and windows closed until the storm front has passed.
