Responders have put out at least two small brush fires in New Hampshire this week amid dry conditions and high winds.

One was in Cornish, near homes on Route 12-A. The other destroyed a barn in Hinsdale.

Fire danger has been rated at least moderate in the state this week. And there's little rain in the forecast in the coming days. The state is well below average on precipitation for the year, with another potential drought in the works this spring.

Combined with gusty winds, the state says it means any open burning can easily catch and spread uncontrolled.

New Hampshire's Department of Environmental Services is expecting air pollution concentrations to reach unhealthy levels in Portsmouth and other seacoast communities.

The outlook for Tuesday is for unhealthy concentrations of ground-level ozone, the main component of smog. The unhealthy air quality comes from the persistence of high temperatures under sunny skies, which can combine with local emissions.

The heat index is expected to flirt with 100 in New Hampshire on Friday and Saturday, prompting health warnings and safety tips from local first responders.

The National Weather Service has heat safety tips.
