Smoke from agricultural fires in the Yucatan Peninsula will affect parts of Texas and Louisiana over the weekend.
Low-level winds will blow smoke from these fires across the Gulf of Mexico to the Texas coastline and southwestern Louisiana.
Smoke from these fires will also affect the eastern Coast of Mexico.
Low-level winds are expected to continue blowing in the same direction over the next few days, resulting in smoky conditions in these areas heading into next week.
According to the Texas Commission on Environmental Quality, smoke from agricultural burning in Mexico and Central America will likely raise the daily air quality index to "Moderate" south and east of a line from Sanderson to Vernon.
This area includes Houston, San Antonio, Dallas, Austin and Fort Worth; the top five populated cities in Texas.
Smoke is also expected to make its way into southwestern Louisiana, which could also raise air quality indexes for parts of the state.
Those sensitive to ozone and other airborne pollutants should exercise caution in these areas.
