Hurricane Florence approaching later this week… Highs will return to the upper 80s this afternoon but it will feel more like the mid 90s with the humidity. We will see a mix of partly to mostly cloudy skies today with scattered showers and storms as a cold front lingers to our west. Severe storms are not expected but thunderstorms and heavy downpours are possible.

We will see partly cloudy skies Wednesday with another chance for scattered showers and storms. Highs will reach the mid to upper 80s tomorrow.

Hurricane Florence will approach the Carolina coastline on Thursday. Based on the current forecast track, we will see widespread rain and very strong winds on Thursday and Friday. Significant flooding is expected with several inches of rainfall combined with coastal flooding and storm surge.

Based on the current forecast track, here is what to expect…


Most of the area will see 5” to 10” of rain over several days (Thursday-Sunday)

Many inland locations will see 10” to 15” of rain

Locally higher totals are possible


Winds will ramp up on Thursday, stay strong through Friday, then slowly relax through the weekend.

Storm Surge

Swells from Florence will impact a large section of the East Coast and are likely to cause life-threatening surf and rip current conditions

Florence will weaken once over land but will linger over the Virginia and the Carolinas this weekend. Winds will slowly relax over the weekend but widespread rain will keep the flooding threat high.

Florence expected to re-strengthen later today. Florence is centered about 390 miles south of Bermuda and moving WNW at 16 mph. A WNW to NW motion with a slight increase in forward speed are expected during the next couple of days. On the forecast track, the center of Florence will move over the southwestern Atlantic Ocean between Bermuda and the Bahamas through Wednesday. Florence will approach the coast of North Carolina or South Carolina in the hurricane watch area Thursday and Friday.
