Radar over South Carolina

Straight from radar.weather.gov and regenerated by NOAA roughly every two minutes.

National Weather Service radar for the Southeast, covering North Carolina, South Carolina, Georgia, Florida and Alabama. — Where precipitation is falling over South Carolina right now. The National Weather Service publishes these mosaics by region rather than by state, so the frame runs past the state line and neighbouring states are visible in it. Radar shows precipitation, not damage — a return over a county is not evidence that any particular building was hit.

Smoke & fire lane

Smoke & fire alerts in South Carolina

The National Weather Service issues a separate family of alerts for fire weather, dense smoke, air quality, blowing dust and volcanic ashfall. This lane reports that family for South Carolina, kept apart from the storm alerts above because the two answer different questions.

Wildfire smoke is what drives smoke-damage losses, and it reaches a building through the same vents that keep an attic dry — which is why it belongs on a roofing page at all. Alerts describing particulate already in the air are listed ahead of fire-weather forecasts; that ordering is this lane’s own and is not a Weather Service ranking.

No active smoke or fire alerts

The National Weather Service has no active fire weather, dense smoke, air quality, blowing dust or volcanic ashfall alerts covering South Carolina as of this refresh.

An empty list here is the ordinary reading, not a fault and not a gap in the data. Most of the country carries nothing in this family on most days, and this lane fills itself the moment the Weather Service issues something.

Smoke exposure and air quality are health matters, and this page does not address them. It does not tell you whether it is safe to be outdoors or to work, what an air quality index number means for you or for anyone in your household, or what respiratory protection to use. Those questions belong with a clinician and with the agency that issued the alert. The federal air-quality authority is airnow.gov.

What smoke does to a roof assembly

An active alert is a record of conditions, not a finding about any building. These are the standing references on the building-assembly side of a smoke or fire loss.

Severe weather season in South Carolina

Peak season

March–May and August–October

South Carolina carries a spring severe season with hail and damaging straight-line wind across the Midlands and Upstate, and a separate tropical season along the coast and coastal plain. NOAA dates the Atlantic hurricane season June 1 to November 30, with the peak from mid-August into October. Tropical systems tracking inland arrive weakened but still deliver sustained wind and wind-driven rain for hours.

Seasons describe a pattern, not a schedule. The National Weather Service issues these products year-round, and the live list above is the only authority on what is actually running in South Carolina right now.

What NOAA has recorded in South Carolina

The archived record, not the live feed. Severe weather logged by the National Centers for Environmental Information over the covered years, split into the events NOAA keys to a county and the events it keys to a forecast zone.

Between 2016 and 2026, NOAA recorded 6,626 county-level severe-weather events across South Carolina: 5,207 thunderstorm wind events, 1,100 hail reports, 318 tornadoes and 1 heavy snow event. Of the 1,100 hail reports carrying a measured size, 624 were 1.00 in across or larger.

A further 1,069 events over the same period were recorded against National Weather Service forecast zones rather than counties — 386 strong wind events, 288 tropical storm events, 132 winter storms, 125 heavy snow events and 101 high wind events. A forecast zone is not a county: it can span several or subdivide one, so these are reported here at state level and appear in no county total on this site.

Preliminary — not yet in the permanent archive

638 further preliminary storm reports have been filed against South Carolina counties since June 1, 2026. They are counted separately from every archived figure above and are not added to any of them.

Preliminary reports covering 2026-05-31 onward come from National Weather Service storm reports filed as events occur. They have not yet been through the quality-control review that produces the permanent archive, and individual reports may later be revised, combined or withdrawn.

County figures and state figures. County figures count events NOAA recorded against a county (hail, thunderstorm wind and tornadoes). High wind, winter storms, ice storms, blizzards, heavy snow, hurricanes and tropical storms are recorded against National Weather Service forecast zones rather than counties, so they are reported at state level instead. Counts reflect events that were observed and reported. NOAA does occasionally record one of those against a county instead. Where it has, the event sits in the county-keyed total above rather than the zone-keyed one — in South Carolina that applies to heavy snow events.

Source. Archived figures come from the NOAA National Centers for Environmental Information Storm Events Database, covering 2016 through May 31, 2026. Reports after that date come from NOAA Storm Prediction Center preliminary storm reports. Both are US Government works in the public domain. This is a record of past weather; the live alert list at the top of this page is the only authority on what is running in South Carolina now.

What these storms do to a roof

The damage mechanisms that matter in South Carolina, in the order they generate work here.

Hail

Hail damages an asphalt shingle in two ways at once. The impact knocks granules off the surface, and it can bruise or fracture the asphalt mat underneath without breaking the surface open. Granules are what shield the asphalt from ultraviolet light, so a roof that has lost them ages faster from that point on. A fractured mat is the reason hail damage is often described as latent: the roof may not leak the week of the storm, and the failure shows up later. On metal panels and metal accessories, hail leaves dents, which raises the separate question of whether the damage is cosmetic or has actually compromised the panel or its coating.

Straight-line wind

Wind damage on a shingle roof usually starts as a broken seal rather than a missing shingle. Uplift pressure is highest at the edges — rakes, eaves, ridges and hips — and along any line where the roof plane changes, so that is where tabs lift and the factory sealant strip lets go first. Once the seal is broken, a shingle that still looks fine from the ground is no longer bonded to the course below it and every later wind event works on the same spot. Wind also drives debris, and impact damage from a branch or from another roof’s material is a separate mechanism from uplift.

Tropical systems

A tropical system combines two things an ordinary thunderstorm does not: wind that lasts for hours instead of minutes, and rain driven sideways into every seam at the same time. The duration matters because uplift is cumulative — a seal that survives one gust may not survive the same gust repeated for six hours. Wind-driven rain also finds its way through vents, ridge products, flashings and wall-to-roof transitions that shed ordinary vertical rain without difficulty. Inland states see the same mechanism at reduced strength when a system tracks in from the coast.

Why the storm date matters

Property insurance works from a date of loss — a specific storm on a specific day over a specific area, not a general observation that a roof looks worn. That is why the county list and the effective and expiry times on each alert above are the useful part of this page: they are the National Weather Service’s own record that a given event covered a given county at a given time.

It also matters because hail damage is frequently latent. A fractured shingle mat can take a long time to become a leak, so the gap between the storm and the discovery can be considerable — and by then, establishing which storm did it is a records question rather than an observation. An alert naming a county is not evidence that any particular building was damaged; it is evidence of what the weather was doing over that county, which is where an assessment starts rather than where it ends.

This site does not edit, summarise or re-grade Weather Service text. Alerts are filtered into two separate lists — the event types that affect roofs, and the smoke, fire and airborne-particulate family — and each list is sorted. Nothing else is changed, and no alert is moved between the two lists to suit a heading.
