Date: August 20, 2014
Work will begin Thursday, August 22 to widen and improve State Road (S.R.) 123 in Okaloosa County. The $48 million construction program will widen S.R. 123 from two to four travel lanes from S.R. 85 near the Northwest Florida Regional Airport to S.R. 85 north of Niceville. Crews will also resurface the existing roadway, construct four new bridges along the route, and build a flyover ramp at the S.R. 123/85 intersection near Niceville.
Drivers will encounter alternating nighttime lane closures on State Road (S.R.) 20, between Roberts Drive and the Walton County line, Sunday, Aug. 17 through Thursday, August 21 from7 p.m. to 5 a.m. as crews work on curbs and sidewalks.
HAZARDOUS WEATHER OUTLOOK:
Elevated heat index values of 102 to 107 degrees will be likely today.
Scattered thunderstorms mainly late this morning and this afternoon may contain brief strong wind gusts in excess of 40 mph, frequent lightning and locally heavy rain. A few strong thunderstorms mostly during the late afternoon or early evening may become briefly severe with localized damaging wind gusts in excess of 60 mph.
There is a moderate risk for dangerous rip currents along area beaches today and tonight.
For the North Atlantic, Caribbean Sea, and the Gulf of Mexico
Disorganized shower and thunderstorm activity is associated with an elongated area of low pressure located several hundred miles east of the southern Windward Islands. Gradual development of this system is possible during the next few days while it moves west-northwestward at 10 to 15 mph across the Lesser Antilles and into the Caribbean Sea. Interests in the Lesser Antilles and the northeastern Caribbean Sea should closely monitor the progress of this system.
Formation chance through 48 hours is medium, 30 percent.
Formation chance through 5 days is medium, 50 percent.
A tropical wave located about 1000 miles east of the Lesser Antilles continues to produce disorganized showers and thunderstorms. Any development of this system should be slow to occur during the next day or two while it moves toward the west-northwest at about 10 mph. After that time, development of this system is not anticipated as it begins to interact with the disturbance located to its west.
Formation chance through 48 hours is low, 10 percent.
Formation chance through 5 days is low, 10 percent.
