| 2026-06-22 | SIDEBURN, VA | 90 | Severe | A severe thunderstorm produced a strong downburst one mile|northwest of Burke VA with peak winds estimated 90 MPH. While|other minor scattered tree damage was noted outside of the|microburst in the general area, the microburst affected the|communities around Lake Royal. Significant concentrated damage|began along Zion Road between the cross streets of Guinea Drive|and Hillard Lake Road. Tree damage continued along Bridgewood|Drive and Falmead Road before reaching Lake Royal. Through this|area, many, though not all, of the trees were snapped midway,|uprooted, or had large branches snapped off. Trees fell onto cars,|powerlines, roads, and homes with substantial damage. Damage was|unidirectionally pushed to the east northeast in the direction of|storm movement.||As the microburst crossed Lake Royal, the lack of trees and|roughness allowed the winds to accelerate and then blast the|townhomes on the east shore. Several townhomes on that row facing|the lake had significant portions of their roofs lifted off. Winds|were estimated to have peaked at 90 MPH.||On the south side of the lake along Guinea Drive, trees were|snapped onto the road and powerlines. A business park building was|noted to have some damage due to the roof being slightly lifted|temporarily.||Significant tree damage continued to the community on the east|side of Lake Royal with similar tree damage along Lakepoint Drive|west of Guinea Road. Trees and branches were again snapped onto|cars and homes, and townhome fences were pushed down on many|properties. East of Guinea Road, winds lessened and tree damage|became isolated. One further point of note was Burke Road near|Peppercorn Drive where a few trees were downed, one onto a bus|stand and street light.||Throughout the survey, damage was pushed to the northeast in the|direction of storm movement. NWS Doppler Weather Radar KLWX in|Sterling, VA, as well as FAA Terminal Doppler Radars from TDCA|and TADW, displayed thunderstorm downburst signatures at the Burke|location at the time, with no evidence of rotation indicating the|storm being tornadic. Severe straight line thunderstorm downburst|wind gusts can sometimes produce damage equivalent to damage from|EF0 and EF1 tornadoes.||Severe thunderstorms can produce wind gusts equal to EF0 and EF1|tornadoes.||The National Weather Service would like to thanks Fairfax County|Department of Emergency Management and Security for their|assistance. |

| 2026-06-22 | ANACOSTIA, DC | 60 | Significant | One tree blew down due to thunderstorm winds at the intersection of Suitland Road Southeast and Southern Avenue Southeast. |
| 2026-06-14 | UNIONVILLE, MD | 81 | Severe | On June 15, 2026, a survey team from the National Weather Service|Baltimore/Washington Weather Forecast Office conducted a formal|storm assessment in Frederick County, Maryland. The objective of|the field survey was to analyze the thunderstorm wind damage that|occurred during the evening of Sunday, June 14, 2026. The event|began at approximately 7:30 PM EDT, when a cluster of showers|initiated in central Jefferson County, West Virginia. This|convective system tracked continuously northeastward into|Frederick County, Maryland, while exhibiting steady|intensification.||As the storm progressed east of Libertytown, Maryland, it|generated a localized zone of significant structural and tree|damage. The most severe impacts were concentrated within the 9000|block of Bessie Clemson Road. Based on the degree of damage|observed, peak wind velocities in this specific corridor were|estimated up to 80 MPH. Physical evidence at the scene included|numerous snapped and uprooted soft and hardwood trees, alongside|the total wall collapse of a barn structure.||Analysis of the debris field and fallen vegetation revealed a|strictly unidirectional damage pattern. This uniform orientation|aligned precisely with the forward motion of the storm, confirming|the absence of rotational characteristics. Therefore, the|National Weather Service Baltimore/Washington Weather Forecast|Office has classified the destruction as a straight-line wind|event driven by downburst winds.||Outside of the immediate Bessie Clemson Road impact zone, the|thunderstorm produced sporadic wind damage across the broader|county. These widespread convective wind gusts were estimated to|range from 60 to 80 mph with all associated damage matching the|directional trajectory of the storm. |
| 2026-06-12 | PENDER, VA | 60 | Significant | A tree blew down at Alder Woods Drive and Joseph Seiwick Drive. |

| 2026-06-12 | 1 WNW Washington, DC | 61 | Significant | Personal weather station in Logan Circle reported 53 kts (61.3 mph) |
The most recent quarter-size-or-larger hail storm recorded by NOAA within 25 miles of Gaithersburg was on June 18, 2025. HailCheck refreshes from the NOAA Storm Events database daily, so newer events appear here as they are reported.
Gaithersburg averages roughly 12 reported hail events per year within a 25-mile radius. Significant storms (quarter-size or larger) account for 58 of the 58 events recorded over the last five years.
The largest documented hail near Gaithersburg in the last five years was egg-sized. Most Gaithersburg-area hail falls in the marble-to-quarter range, with destructive storms (egg-size or larger) appearing roughly once every few years.
Most homeowners insurance policies in MD cover hail damage to roofs, siding, and gutters under the dwelling and other-structures coverage. Coverage typically requires the damage to be tied to a verifiable storm date — which is where the NOAA hail history above (and a HAAG-style test square validation) becomes important for the claim file.
Use the HailCheck address search to enter any street address in or near Gaithersburg. HailCheck returns every NOAA hail event within a configurable radius, along with severity bands, dates, and storm narratives for Pro members.
If your property in or near Gaithersburg took on hail during one of the storms above, the standard process for documenting damage is a 10×10 foot test square inspection. A HAAG-trained reviewer counts impact indicators — granule displacement, mat fractures, and bruising — within the marked square and produces a PASS or FAIL document for the claim file.
HailCheck offers a $99 photo-based HAAG-style test square validation. You submit photos from the field, our reviewer evaluates the impact indicators and cross-references the NOAA storm dates listed above, and a written PASS/FAIL determination is returned within one business day. We do not send anyone to the roof — the validation is built around the photos you submit.
Learn About $99 HAAG-Style ValidationGaithersburg sits east of the traditional hail alley, where hail events are less frequent than the central plains but tend to be associated with strong squall lines and tropical systems. Local roof systems are less commonly hardened for hail, which can mean even moderate impacts produce claim-worthy damage.
