Discoveries
buried root obstruction at depth in lee slope clay; prevents auger testing without excavation
clay saturation extends more than 30cm below current French drain trench at west garden wall corner
grandmother's seed tin packets mostly viable despite rusted tin; only minor edge mold on three packets
Sea beet morphology shows high salt-tolerance variations.
garden wall north end weeping; intercept trench functional but clay saturated
The water tank is full at 400 litres.
The hilltop garden patch pH is 5.6, indicating acidic soil requiring lime amendment.
The barometer is dropping by 3 hPa in minutes, indicating the squall is intensifying.
The atmospheric pressure is dropping steadily, indicating an approaching storm before the supply boat arrives.
Barometer dropping faster than predicted — 3 hPa in minutes with the squall
Coconut crabs are gnawing the new oak shade cloth stakes overnight
The pressure drop is faster than the last storm.
sheltered garden patch near cottage tests pH 6.2 — still too acidic for Cananga
loft floorboards remain dry; seed tin seal effective against humidity
heavy southwest swell running at high tide; ridge visible but low cloud obscuring detail
Swell arriving ahead of predicted tide; gap under jetty already taking water at rising tide
Sheltered garden patch near cottage tests pH 6.2 — viable for planting without lime amendment
rain barrel catchment impaired — half full in heavy rain indicates gutter or screen blockage
garden wall soil pH 6.2 — lime amendment helping but still below 6.8–7.0 target for heirloom vegetables
grandmother's seed tin desiccant still active; all heirloom packets viable despite crate immersion; tin seal held
south piling rot extends 15cm inward at waterline but sound timber reached at 4 inches depth; percussion confirms hollow ring only in outer shell
coconut crab active in garden overnight, targeting metal and cedar hardware
south piling rot extends at least 15cm inward at waterline with hollow ring on percussion
Soil pH near garden wall remains acidic at 5.6, consistent with cottage foundation readings
The atmospheric pressure drop indicates a significant storm front is moving in.
The storm is moving faster than the barometer suggested a few hours ago.
The volcanic outcrop is stable for now, but the surrounding soil is saturated.
The northern slope pooling zones are becoming more saturated as the atmospheric pressure drops.
Lessons learned
If the clay is turned to soup, stop using mechanical fasteners; work with the weight of the earth instead.
Keep the radio tuned to 8764 kHz every morning to catch the supply boat schedule.
If the barometer drops by 5 hPa, I’ll finish the French drain before the storm hits.
Humidity is the primary enemy of seed viability; keep the tin sealed and inspect daily daily.
If the clay is saturated below the trench depth, stop using mechanical anchors; wait for the drainage or pivot.
If the clay's saturated past trench depth, no anchor holds — dig the French drain to the sand layer or don't bother.
If the soil is a slurry, don't fight the structural integrity; wait for the lee slope to offer the drainage.
If the barometer drops below 985 and the clay's saturated past 30cm, stop digging — the trench walls will collapse. Wait for three dry days or shore it with planks.
If the clay saturates past 60%, no trench holds — plant on the lee slope microsite where volcanic grit keeps drainage sharp
How to read aloud so it steadies both of you: slow, even, don't perform. Let the words do the work.
If the north trench clay stays saturated past 72 hours, dig the secondary spillway at the west corner — the bamboo stakes mark it.
Don't try to out-dig silt with trenches; find the natural drainage or lose the slope.
If the barometer drops below 980, batten the west roof corner first — it catches the worst of the westerlies
Barometric drops are a warning, but the behavior of the tide tells you the actual timeline.
If the garden wall is weeping at the lower courses, the hydrostatic pressure is already bypassing your drainage; stop digging start reinforcing.
If the intercept trench silts within one tide cycle, dig the overflow channel deeper before the next spring tide — don't wait for the wall to weep
Acidic soil at pH 6.2 will choke delicate seeds before they have a chance to root.
If the barometric pressure drops faster than the morning reading, ignore the schedule and secure the water tanks immediately.
Hydraulic cement on foundation fissures needs the ebb tide window; flood tide washes it out before it sets
If the barometer drops more than 3mb in six hours, the front moves twice as fast as forecast — secure everything before noon
If the rain barrel is only half full after a downpour, the drainage is diverting elsewhere.
Use greenheart for structural repairs because the salt-rot moves faster than any local timber.
If the gutter screen clogs, the tank overflows before the barrel fills — check it at every tide change during sustained rain
If the barometer drops below 985, stop worrying about the garden and move the dry gear to high ground.
If epoxy fails on a saltwater tank, fiberglass mat over the seam buys weeks not days — but only if the surface is bone dry and grease-free first
Plant grandmother's seeds in volcanic ash microsites only — everything else on this island is transient.
If the barometer drops below 990, seal the northeast window the night before — epoxy fails under sustained pressure differential.
Epoxy tape on poly tanks buys twelve hours max in heavy weather; need proper welding kit or spare tank
If the barometer drops below 980 and the wind backs northeast, batten everything by 1000 — the window seal fails at 45 knots sustained
How to test soil stability: dig 40cm, check for distinct horizons, taste for salt, observe indicator species at root zone. Volcanic ash over bedrock with spring drainage = only ground that won't move.
If the barometer drops below 990 hPa and tide recedes abnormally fast, the storm surge will reshape shoreline within hours — map new salt lines immediately after.
If the barometer holds above 985 past midnight, the storm breaks soft. Prep for the forecast anyway.
