Dense smoke, heat advisories issued

SAVANNAH, GA (WTOC) -

A dense smoke advisory in effect until 2 p.m. Thursday. The dense smoke advisory includes Glynn, McIntosh and Liberty counties. 

A heat advisory is also in effect until 8 p.m. Thursday. The heat advisory includes these Georgia counties: Chatham, Bryan, Liberty, McIntosh. It includes these South Carolina counties: Jasper and Beaufort.

Dense smoke with visibilities of 1 mile or less will continue through early afternoon. Visibilities may drop to a half-mile or less at times. In addition, high humidity values and temperatures well into the 90s will produce heat index values of 105 to 110 degrees this afternoon into the early-evening hours. 

Poor air quality can be expected within the smoke. The combination of heat and humidity could also produce heat related illnesses.

The dense smoke advisory means fires will create smoke thick enough to greatly reduce visibilities. Drivers should use caution and allow for extra travel time. Use low-beam headlights and reduce driving speeds. Leave plenty of distance ahead of you in case a sudden stop is needed. Follow instructions of traffic control authorities. 

The NWS is urging those who are spending time or working outside to take extra precautions if you work or spend time outside. Reschedule strenuous activities to early morning or evening; know the signs and symptoms of heat exhaustion and heat stroke; wear light weight and loose fitting clothing when possible and drink plenty of water.

To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location.
