In Acadia National Park, a gust uprooted a mature tree that had a small, shallow root ball, as many do in a wet climate and soft soil. That alone is not too remarkable, nor is it that the tree fell across a smaller one and broke it. [In this website, you may find a huge, tree-busting branch fall from an ice storm in Oklahoma, and general mass treefall from a gradient-wind event in the Olympic … [Read more...]
Autumn Rapids on Joes Brook
A rainy day bolstered the flow of a Vermont creek, pushing good flow over shallow ledges of metamorphic rock, and making a soothing sight and sound from the dry shelter of the late-1800s Greenbanks Hollow Covered Bridge. Hey, if you're going to do photography in the rain, why not be under a roof? Lower light levels under the overcast conditions allow longer exposures and better feathering of … [Read more...]
Potwin HP
Seeing this churning along to one's west can be a dream or nightmare—perhaps both at once. To the farmer, a heavy-precipitation supercell brings plenty of rain, but also, the risk for hail, severe wind, and flooding, all of which are not good for crops. To the storm observer, the darkening, low-visibility and increasingly thunderous western skies bring an aura of mystery and danger, especially … [Read more...]
Menacing Ark City
A previously unassuming, strung-out and poorly organized supercell hit a plume of greater low-level moisture and vorticity, accompanying a modified outflow boundary from the previous night's thunderstorms. It got happy quickly. This wall cloud formed fast and rotated strongly. The front-lit scud lowering in the foreground raced left to right as cloud material in the background pulled the other … [Read more...]
Busted Trees at NWC
The October 2020 ice storm snapped many tree branches across the National Weather Center's grounds, certainly including unaccustomed nonnatives like these Chinese pistachios. The early-season (fall) ice storm wasn't large in magnitude, with accumulations generally around 1/4 to 1/3 inch here. However, because it happened while so many leaves still were green, or just starting to change color, … [Read more...]
Indirect Sunrise Color
This would become a spectacular sunrise over Mount Desert Island, but was well on its way even here. The sun still was below the horizon, even from the perspective of the altocumulus and altostratus cloud deck's underside! So how did it redirect such a rusty, chocolate-red tint? This was all indirect light, reflected from distant, unseen, directly lit clouds over the horizon and far out over … [Read more...]
