Tropical Cyclone Idai has formed in the Mozambique Channel and will bring flooding rain and strong winds to Madagascar and parts of the Mozambique coastline into the middle of the week.

The storm will remain in an area conducive for strengthening over the next couple days.

The warm water, in combination with lower wind shear over the region, has produced ideal conditions for Idai to continue intensifying into a more powerful tropical cyclone.

During the early week, Idai will stall just west of Madagascar before eventually turning back westward toward Mozambique.

While the strongest winds will remain offshore during this time, gusty winds are expected from near Mahajanga southward to Mainirano. A few gusts up to 80 km/h (50 mph) are possible during this time.

Areas that experience a prolonged onshore wind will also be at risk for coastal flooding. Rough surf and seas will also be a concern along the west coast of Madagascar into early week.

Heavy rainfall will be another concern across northern and central Madagascar as downpours target the region each day through Thursday, despite Idai tracking away from the island by the middle of the week.

Total rainfall of 50-100 mm (2-4 inches) is expected across the region with an AccuWeather Local StormMax of 200 mm (8 inches) from Soalala to Maintirano.

Following a weekend of strong winds, rain and snow, another storm will bring the risk for flooding and damaging winds to parts of the British Isles in the coming days.

The storm will also bring the risk for damaging winds to parts of Belgium, Netherlands and Germany from Tuesday into Wednesday.

If this storm is given a name by the Met Office or Met Éireann, it would be called Gareth, and become the seventh-named windstorm of the season.

Locations from western Ireland into western Scotland will be the first to be impacted by the storm as rain and increasingly strong winds arrive Monday afternoon.

"The heaviest rain is expected from western Scotland into northwest England and northern Wales and from Monday evening into Tuesday," said AccuWeather Meteorologist Tyler Roys.

"Rainfall amounts of 25-50 mm (1-2 inches) are expected in these areas, with an AccuWeather Local StormMax™ of 75 mm (3 inches)," added Roys.

Recent rainfall in addition to the downpours from this storm will elevate the risk for flooding.

In addition to heavy rain, winds will become gusty during the day on Monday before becoming locally damaging from Monday night into Tuesday and Wednesday across Ireland and the United Kingdom.

After slamming Ireland and the United Kingdom, strong wind gusts will stretch to France, as well as parts of Belgium, Netherlands and northwestern Germany from Tuesday into Wednesday.

The highest wind gusts, at a magnitude of 95-110 km/h (60-70 mph), are expected in western Scotland, Northern Ireland, western Netherlands and far northwest Germany.

These winds can produce widespread power cuts and travel disruptions with a localized risk for damage to homes and businesses.

Wind gusts 65-80 km/h (40-50 mph) are expected in London and Paris while Brussels and Manchester could see a wind gust as high as 95 km/h (60 mph).
