Category 5 Dorian is sitting over Grand Bahama

/ September 2, 2019 at 6:44 AM

As of the 5am advisory, Hurricane Dorian remains a powerful Category 5 hurricane with maximum sustained winds of 165 MPH. It has essentially stalled out, crawling to the west at 1 MPH. It is expected to very slowly start moving more northward today. Impacts for the Lowcountry — storm surge, strong winds, very heavy rain — are becoming a little clearer, but everything hinges on when the northerly turn happens. More later this morning.

Dorian at 5PM: Dangerous storm continues to lash the Bahamas

/ September 1, 2019 at 5:19 PM

At 5PM, Hurricane Dorian was over the Bahamas, packing incredible winds of 185 MPH (with gusts to 220 MPH). It continues an ever-slower westward motion of 5 mph. The storm is expected to nearly stall out on Monday as steering currents weaken, then it is forecast to make a turn to the north sometime late Monday or Tuesday.

The situation with respect to Charleston has not yet changed, and preparations for hurricane conditions on Wednesday and Thursday should be ongoing.

[UPDATED] Dorian: Monster storm

/ at 12:04 PM

At 4 PM, Hurricane Dorian tied the third-strongest hurricane on record, the 1924 “Cuba” hurricane, in the Atlantic basin by pressure with a barometer reading of 910 millibars. Max winds are estimated at 185 MPH with gusts to 220 MPH. It is lashing the Bahamas with extreme wind and storm surge as it continues to slow down. We are watching intently to see when the storm will turn north. (The sooner, the better.)

The storm continues to pose a threat to the Southeast coast, including Charleston, for the middle of next week. Preparations for hurricane conditions should continue in the Charleston area, with the risk for greatest impacts Wednesday afternoon into Thursday.

The next full track and intensity forecast will be out at 5PM.

Tropical Storm Dorian formed over the weekend, fighting dry air as it approaches the Lesser Antilles. It has a highly uncertain road ahead of it, but it may be something to watch as we get into next week.

Hot start to the second half of 2019

The second half of 2019 will get off to a fairly hot start, with heat indices running in the low 100s each afternoon. Scattered thunderstorms will provide relief, particularly later in the week. (Must be July in Charleston.)

The Atlantic hurricane season begins today

/ June 1, 2019 at 10:00 AM
2019 storm names.

Welcome to the 2019 Atlantic hurricane season, which begins today (June 1) and lasts through November 30. This is the climatologically favored time for tropical systems to develop in the Atlantic basin (though we have had our fair share of May storms, including Subtropical Storm Andrea a few weeks ago). A fact of life of living in the Lowcountry — which is a really wonderful place! — is that we are susceptible to tropical cyclones, and as such, must be prepared for the possibility that one may approach the area.

Records safe today as thunderstorm chances increase

/ May 31, 2019 at 8:03 AM

It’s been a while since I’ve been able to say this, but here goes:

The record high of 98°, set in 1953, is safe today.

Temperatures will only top out in the mid-90s before thunderstorms — yes, thunderstorms with actual rain — start to develop by mid-afternoon. A few of these thunderstorms may be on the strong side, though.

Another day, another record

/ May 29, 2019 at 12:08 AM

We continue to rewrite the record books as a strong ridge of high pressure remains firmly entrenched over the Charleston area, with three straight days of 100° temperatures and counting. The streak may continue for one more day, followed by a gradual falloff of temperatures (and a small increase in shower and thunderstorm chances) as we get into the weekend.

Two 100° days down, perhaps one to go, then a “cooldown”

/ May 28, 2019 at 7:37 AM

After a record-breaking Memorial Day weekend, the heat wave continues as stifling high pressure remains in force over the Charleston metro area. Temperatures approaching the century mark away from the immediate coast are once again expected. While heat indices will not pose a major issue, low humidity will instead elevate the wildfire risk. Changes are coming later this week, though.
