Tropical Storm Melissa Forecast: Jamaica, Ireland, Britain

If you’ve been watching the tropics this week, the name Melissa keeps showing up in forecasts and news alerts. This storm has already earned its place as one of the most closely watched systems of the season, with the potential to affect millions from the Caribbean to Ireland and Britain.

Current Classification: Tropical Storm (NHC) ·
Expected Peak Strength: Major Hurricane (Category 4/5) ·
Area of Concern: Caribbean Sea, Jamaica, Cayman Islands, potential trajectory toward Ireland and Britain ·
Forecast Source: National Hurricane Center, AccuWeather, Weather Underground

Five key facts define Melissa’s current state and the immediate forecast.

The pattern: Melissa is still gathering strength, and its next 48 hours will determine whether it becomes a catastrophic hurricane or a more manageable storm.

Where is storm Melissa going to hit?

Current location and movement

• Tropical Storm Melissa is currently over the central Caribbean Sea moving west-northwest – Met Office (track update)
• According to the National Hurricane Center, the storm is expected to strengthen into a major hurricane within 48 hours – TheJournal.ie (NHC forecast)

Projected path over the next 5 days

• The forecast cone from the National Hurricane Center shows the storm passing near Jamaica, then moving over Cuba and the south-east Bahamas – Eos (track map)
• After that, models diverge: some show a northward turn towards Ireland and the UK, others keep it west – Met Office (uncertainty)

What this means: The window for Jamaica to prepare is closing fast, while Ireland and Britain are watching a longer-range threat that depends entirely on the storm’s mid-Atlantic turn.

Is storm Melissa going to hit Ireland?

Expected arrival time of the storm’s tail

• Professor Peter Thorne of Maynooth University said that if Melissa impacts Ireland, it would likely be at the end of the weekend or early the next week – TheJournal.ie (meteorology expert)
• The Met Office notes that forecasts suggest Melissa will encounter cooler waters and drier air as it moves north-northeast, causing weakening – Met Office (deep dive)

Potential weather conditions for Ireland

• Met Éireann said Melissa’s remnants would likely bring “plenty of rain and unsettled weather” to Ireland later in the week – TheJournal.ie (Met Éireann statement)
• However, Professor Thorne added it was “too soon to tell” what the exact effects would be – TheJournal.ie

The trade-off: The later Melissa arrives, the weaker it will be — but the more rain it can dump on already saturated ground.

Is Hurricane Melissa a threat to Jamaica?

Jamaica’s hurricane watches and warnings

• Jamaica is under a hurricane watch as Melissa approaches – TheJournal.ie (NHC advisory)
• The U.S. National Hurricane Center warned of “catastrophic winds, flash flooding and storm surge” – TheJournal.ie (NHC quote)

Preparations and safety measures

• The International Red Cross said the storm could affect up to 1.5 million people in Jamaica – TheJournal.ie (Red Cross estimate)
• Many areas of Jamaica are likely to see over 500 millimetres of rainfall, with some parts possibly exceeding 750 millimetres – Eos (rainfall analysis)
• The Met Office said Melissa could bring up to 1,000 millimetres of rain over its lifespan, with Jamaica, Cuba, Haiti and other parts of the Caribbean facing the brunt – Met Office (rainfall total)

Why this matters: Jamaica is in the direct line of a rapidly intensifying storm. The combination of extreme rain and mountainous terrain creates a high risk of deadly landslides and flash floods.

Will storm Melissa affect Britain?

Forecast impacts on the UK

• The Met Office said the UK is unlikely to experience the full force of Melissa, but could still see unsettled conditions – Met Office (UK outlook)
• Wet and windy weather could affect parts of the UK, particularly the northwest – Met Office (regional detail)

Met Office outlook and warnings

• The Met Office released a ‘Deep Dive’ video on Hurricane Melissa and UK weather, highlighting the uncertainty – Met Office (deep dive)
• There remains uncertainty about Melissa’s exact Atlantic track, with some models suggesting a possible approach toward the UK or Iceland – Met Office (model spread)

The implication: The UK and Ireland are watching a storm that could fizzle out or re-intensify — both outcomes are still on the table.

Where is Hurricane Melissa now?

Latest coordinates and intensity

• As of the most recent advisory, Melissa is a tropical storm with maximum sustained winds near 70 mph – FOX 5 NY (NHC advisory)
• The storm is expected to strengthen into a major hurricane within 48 hours – TheJournal.ie (NHC forecast)

Tracker tools and live updates

• Live tracker maps show the storm’s path and forecast cone – Weather Underground (hurricane tracker)
• NOAA provides official satellite imagery and data – National Hurricane Center (official site)

The bottom line: Right now, Melissa is a tropical storm, but it has all the ingredients to become one of the strongest hurricanes of the year. Every hour of monitoring counts.

“AccuWeather meteorologists expect Melissa to become a major hurricane and could reach Category 4 or 5 intensity.”

— AccuWeather via TheJournal.ie (forecaster analysis)

“The Met Office Deep Dive video discusses Hurricane Melissa and the UK weather outlook, noting possible impacts.”

— Met Office (deep dive meteorologist)

“Hurricane Melissa was the strongest tropical cyclone of 2025, with highest winds of 190 mph (305 km/h).”

For residents in Jamaica, the next 48 hours are critical: finalise preparations, heed evacuation orders, and stay tuned to local authorities. For those in Ireland and Britain, the storm’s remnants may bring a wet and windy end to the week, but the exact severity is still up in the air. Major storm events in Ireland have taught us that even ex-hurricanes can cause disruption, so checking Met Éireann 10-day forecasts and staying informed is the smart move. For Jamaica, the choice is clear: prepare for the worst, hope for the best.
