Houston Haze: Agricultural Burning in Mexico Affects Local Weather and Air Quality

Source of Houston's Haze

• 💨 The hazy skies observed in Houston are primarily due to agricultural burning occurring in Mexico and Central America.
• 🗓️ This burning season typically runs from March to May, preparing land for the growing season from June through October.
• 🌬️ Strong south winds are carrying the smoke from these fires across the Gulf of Mexico towards Texas.

Impact on Houston Weather

• 🌡️ The smoke haze can limit afternoon high temperatures, causing them to be a few degrees cooler than forecasted, potentially by 3 to 4 degrees Fahrenheit.
• 📈 Even with forecasts for mid to upper 90s, the haze might bring temperatures down by approximately two to three degrees.

Visual Evidence and Duration

• 📸 Live views of areas like the Galleria show visible haze in the distance.
• 🔥 NASA's FIRMS viewer indicates numerous active fires in the region, with upper-level winds directing smoke towards Texas.
• ⚠️ This hazy condition is expected to persist at least through the weekend, including Friday and Saturday.

Air Quality Concerns

• ☁️ Current air quality in Houston is rated as moderate.
• ⚠️ While not yet at sensitive or unhealthy levels, the smoke could potentially lower air quality further.
• 😷 Individuals sensitive to lower air quality levels may want to limit outdoor activities.

Overnight Conditions
