🔴 LIVE UPDATES

(Updates will be added as Joseph develops and its UK impact becomes clearer)

🌦️ Storm Joseph: 1:47 PM Update on Thursday 29th January

• The “Double-Whammy” Effect: While Storm Chandra provided the initial wind and rain earlier this week, the trailing edge of Storm Joseph (currently hammering Portugal) is acting as a “moisture pump.” This is funneling additional heavy rain across the English Channel and into the South of England.
• Record Rainfall in the South: Parts of Dorset have seen three times their monthly average rainfall in just 48 hours. Meteorologists confirm that while the wind is from Chandra, the sheer volume of water is being reinforced by the atmospheric river linked to Joseph.
• Hydro Lag Warning: Experts warn that even as Storm Joseph moves further into mainland Europe, the “hydro lag” means UK river levels (specifically the Stour and Avon) will continue to rise throughout Thursday and Friday.
• Travel Disruptions: Residual gales linked to the wider low-pressure system (Joseph/Kristin) are still causing cancellations for ferry services in the Irish Sea and delays for short-haul flights to Southern Europe.

Storm Joseph: Outlook for Thursday, 29 Jan

The Met Office has confirmed that while the storm’s core is hitting Spain and Portugal particularly hard, its associated frontal system will sweep across the UK tomorrow.

🌧️ Rain & Flood Risks (The South West Focus)

• New Yellow Warning: A Met Office yellow rain warning is in place for Cornwall, Devon, and Somerset starting Thursday afternoon.
• Accumulations: Expect 10-15mm widely, with up to 25mm on high ground (Dartmoor/Exmoor).
• The “Saturated Ground” Multiplier: Because of Chandra’s record-breaking rainfall, the Environment Agency warns that even these modest amounts of rain could trigger immediate surface water flooding and cause already swollen rivers to overtop again (ITV News).
• Somerset Levels: Pumping operations at Northmoor and Saltmoor are struggling to keep up. Expect further road closures on the Levels tomorrow evening.

❄️ Snow Potential (The North & Wales)

• Upland Snow: As Joseph’s rain moves north and meets colder air, it is expected to turn to snow over the Peak District, Pennines, and Lake District.
• Wales: Up to 11 hours of snow is forecast for the hills of Northeast Wales (Clwydian range and Berwyn mountains) starting Thursday night into Friday morning (Wales Online).

🚗 Transport & Infrastructure

• Dawlish Sea Wall: Speed restrictions remain in place following the structural damage reported yesterday.
• Evacuations: Residents at Iford Bridge Home Park (Dorset) who were evacuated today are advised to remain away from their properties through Thursday as river levels on the Lower Stour are not expected to recede quickly (Environment Agency).

📌 Storm Joseph Preparation: Tomorrow’s Checklist

• ☑️ Sandbag Check: If you are in a low-lying area of Somerset or Dorset, ensure your barriers are in place by 14:00 Thursday before the next band of rain arrives.
• ☑️ Commuter Alert: Check for “flash” closures on the A35 and A352 in Dorset tomorrow evening—these roads are currently highly susceptible to even light rainfall.
• ☑️ Power Bank Top-up: Wind gusts associated with Joseph could reach 45-50mph in coastal areas; combined with waterlogged roots, this increases the risk of trees falling onto power lines.
• ☑️ Livestock Management: If you have animals on the Somerset Levels, ensure they are moved to high ground tonight, as pumping operations are currently at maximum capacity.

🧠 UK Prepper Hub Tip: The “Lag Time”

Remember that the peak flood risk often occurs 24-48 hours after the rain stops. Even if tomorrow’s rain seems “light,” the water falling on the hills of Devon and Somerset takes time to travel down into the valleys. Stay vigilant even if the sun comes out briefly tomorrow morning.

Current Status (11:20 GMT, 28 Jan)

Just as Storm Chandra batters the UK, Storm Joseph is already named by the Portuguese meteorological authority (IPMA). Currently pummeling Spain and Portugal with red-level alerts, Joseph will not directly impact the UK—but it will send moisture northward, potentially enhancing rainfall across an already-saturated Southwest England.

This post tracks Joseph’s development and any secondary impacts to UK weather over the coming days.

• Joseph making landfall on Spanish coast with red-level alerts issued by Spanish authorities
• UK Met Office maintaining “no direct storm impact” forecast for UK
• Southwest England flood alert status: Monitoring for potential enhancement
• No new storm warnings issued for UK at this time

Where Did Storm Joseph Come From?

Storm Joseph originated as a deep area of low pressure in the Atlantic, tracking eastward toward the Iberian Peninsula. The system has been named by Portugal’s meteorological authority (IPMA) as it intensifies over the Atlantic before making landfall on Spain and Portugal.

Unlike Chandra, Joseph is smaller in scale and more southern in track. However, its positioning means Atlantic moisture will be channeled northward toward already-saturated UK regions.

---

Current Storm Joseph Status

• Location: Moving across Spain and Portugal (Jan 28)
• Intensity: Strong Atlantic storm (Iberian-focused)
• UK Track: Will track southward and miss direct UK landfall
• Key Risk: Moisture feed → enhanced rainfall for Southwest England

---

What Does Joseph Mean for the UK?

Southwest England (Primary Concern)

The greatest impact will be felt in South Devon, South Somerset, Dorset, and Cornwall—the same regions already battered by Storm Chandra.

Expected:

• Additional rainfall of 10-20mm (lower levels)
• Moisture enhancement from Joseph feeding moisture northward
• Timing: Late Wednesday Jan 28 through Thursday Jan 29

The Real Risk: Ground saturation from Chandra + additional Joseph moisture = continued flash flood potential, particularly in river catchments that haven’t yet peaked.

Rest of UK

Minimal direct impact. The forecast for Wed 28 Jan – Fri 30 Jan shows changeable weather with spells of rain and hill snow possible in the north, drier in the east on Wednesday with some sunny spells, feeling chilly with temperatures around seasonal average.

Northern regions and Scotland may see some benefit from Joseph’s moisture, but no significant storm-force impacts.

Key Points for Southwest Residents

You’re not facing another Chandra or Ingrid. Joseph will not directly hit the UK. However:

• ✅ River levels peaked by Chandra may not have fully receded
• ✅ Additional rainfall from Joseph could trigger secondary flash flooding
• ✅ Keep monitoring local flood alert updates through Thursday
• ✅ Avoid driving through standing water or flooded roads

---

The Bigger Picture: The Storm Sequence

Storm Joseph is part of a multi-week pattern:

1. Storm Ingrid (Jan 22-23) – Initial deluge, ground saturation
2. Storm Chandra (Jan 26-27) – Major impact, 330+ flood warnings
3. Storm Joseph (Jan 28-29) – Secondary moisture feed
4. Storm Kristin (Following Joseph) – Potential stacking effect

This isn’t isolated weather events—it’s a persistent Atlantic pattern delivering moisture week after week. Southwest residents and anyone in flood-prone areas should remain vigilant.

🧠 UK Prepper Hub Tip

If you’re in the Southwest:

• Don’t relax just because “it’s not another Chandra.” Secondary rainfall on saturated ground can still cause problems.
• Monitor your local river gauge rather than waiting for official alerts. You’ll see the water rise before alerts are issued.
• Keep your Grab Bag accessible—this pattern isn’t over yet. January still has days left, and the forecast continues beyond this week.
• Document your property NOW (photos/video) if you’re in a flood risk area. Insurance will need evidence of any additional damage.
