High levels of sulfur dioxide on the Big Island prompts another health warning from the state. The air is still smoky and hazardous over parts of the Big Island and that could cause breathing problems, especially for people with respiratory conditions.

The Halemaumau vent near the summit continues to erupt ash and sulfur dioxide emission rates have again gone up.

The state health department is advising people to stay indoors if possible and drink plenty of fluids.

Here is the official message from Hawaii Civil Defense:

On Halema`uma`u, Hawaiian Volcano Observatory reports that activity at the vent in the crater continues. Over the past week, sulfur dioxide emissions have been fluctuating. Monday's sulfur dioxide emission rate was about one-half of the emission rate a week ago. Scientists at HVO caution, however, that this is still quite a bit above the normal rate and does not necessarily represent a trend to lower emission rates. On ash, reports indicate that ash emissions from Halema`uma`u seem to be relatively constant.

On wind conditions, the National Weather Service forecast at this time is for the trade winds to continue for the next few days. Do remember that wind forecasts can change, so please do keep yourself updated.

On emissions and air quality:

• On vog, field reports indicate that vog levels are occasionally high in several districts. This is primarily on the west side.
• On ash, reports indicate light ash is still reaching Pahala.
• On sulfur dioxide, the State Department of Health reports that recently the 24-hour sulfur dioxide level recorded in Pahala has exceeded the federal ambient air quality standard. Due to this, if you have pre-existing respiratory conditions and live or work in an area affected by increased levels of sulfur dioxide, do take precautionary measures. For more information log on to the Department of Health website.

The following are general recommendations from the American Lung Association:

• Stay indoors and use an air conditioner, if available.
• Limit physical exertion.
• Drink plenty of fluids.
• If you take medications, make sure you have an adequate supply and keep them readily available.
• Contact your physician right away if any respiratory problem develops.

You are advised to keep yourself informed, be aware, and take self-protection measures as necessary. The volcanic conditions will be closely monitored and if any changes occur that might affect your safety, you will be informed.
