Shelby County Emergency Management officials say as the winds subside, and precipitation is in the forecast for Friday, they will change the Fire Danger Level in the County to the MODERATE category, until Monday.  They caution Fire Chiefs, however, that the air mass will be in place with very little venting which means smoke from controlled burns will remain in the area for extended time frame.  If someone wants to do a larger controlled burn that could cause some visibility and health issues adjacent to the burn area.
