Hawai`i County Civil Defense reports on Monday morning that light easterly winds are expected to push volcanic gases and vog westward towards Puna, including Kurtistown, Mountain View and Glenwood.
This wind pattern, combined with occasional bursts of ash from the Kilauea summit, may lead to build up of ash and sulfur dioxide downwind of the Kilauea summit and fissures on the East Rift Zone.
Hawai`i County Civil Defense says residents should take action to limit exposure to ash, volcanic gases, and VOG; be prepared to leave the area with little to no notice.
In addition, it is suggested to limit outside activities and exercise and rink plenty of fluids.
If you have breathing problems, stay indoors with the windows closed. If possible, use your air conditioner.
Ash and vog may decrease visibility, so adjust your driving to the conditions.
N-95 masks that were distributed are for ash particulate and do not protect from gasses or vapors, including SO2.
