... High Wind Warning in effect from 4 am to 10 PM EST Wednesday...
The National Weather Service in Jackson has issued a High Wind Warning... which is in effect from 4 am to 10 PM EST Wednesday.
* Timing: southerly winds will increase late tonight. A line of showers... and perhaps a few thunderstorms... will accompany a cold front into the area towards dawn. Any showers or thunderstorms will likely contain strong... damaging wind gusts. Strong and potentially damaging winds will then shift to the southwest and continue for several hours behind the front on Wednesday.
* Winds: gusts up to 60 mph will be possible with any showers or thunderstorms late tonight and early Wednesday morning. Sustained winds from the southwest will then increase to between 25 and 35 mph behind the front on Wednesday. Gusts up to 60 mph are expected for a several hour period behind the front... likely extending into the early afternoon hours. Wind speeds will then gradually subside through the afternoon and evening... but gusts up to 50 mph will remain likely into the early evening hours.
* Impacts: tree damage is highly likely with winds of this magnitude after rainfall late today and tonight saturates the soil. The falling trees will likely down power lines... resulting in the possibility of prolonged power outages. Damage to structures and unsecured objects and property is also possible. Drivers of high- profile vehicles on north-to-south roadways... such as US 23 and Interstate 75... may also have extreme difficulty on Wednesday.
Precautionary/preparedness actions...
A High Wind Warning means a hazardous high wind event is expected or occurring. Sustained wind speeds of at least 40 mph or gusts of 58 mph or more can lead to property damage.
