storm
To protect (seed-hay) from stormy weather by putting sheaves of them into small stacks.
storm: to stack hay against weather damage
To storm means to gather freshly cut hay or seed-hay into small, compact stacks called stooks or shocks, arranged to shed rain and wind during the curing period. The practice protects the crop from being flattened, tangled, or washed away by heavy rain or wind before it dries enough for baling or threshing.
The technique requires standing sheaves upright and leaning them together in a tent or cone shape, typically four to eight sheaves per stook depending on stem thickness and local custom. Seed-hay, which must retain its seed heads intact, is particularly vulnerable to weather damage during cure; storming it keeps those seed heads elevated and exposed to air circulation while protecting them from mud splash and rain saturation.
Storming differs from simply casting hay in windrows or heaps. A properly stormed stack has an internal structure that allows air to circulate while the outer sheaves shed water like roof tiles. The base is often widened slightly to prevent the stooks from tipping in wind, and they are spaced far enough apart that a person can walk between them to monitor drying progress.
Timing and regional use
The practice is most common in cooler or maritime climates where hay cure is slow and sudden wet weather is frequent. It is less common in arid regions where hay dries quickly in the sun and wind. The term remains dialectal, particularly used in parts of Scotland, northern England, and traditional hay-making regions of northern Europe, though the physical practice is older than the terminology itself.
Storming must be timed carefully. Hay cut too wet will mold inside the stook; cut too dry, the leaves shatter and quality drops. The decision to storm depends on weather forecast, humidity, stem diameter, and how soon baling equipment will be available. Once the hay reaches proper moisture content (typically 15 to 20 percent for baling), the stooks are opened out again to spread on the ground, or taken directly to the baler.
