The first windstorm of the season could blast the northern United Kingdom around Tuesday of next week as Karl arrives.
After strengthening into a hurricane over the Atlantic Ocean this weekend, Karl will continue to produce hurricane-force winds early next week even as it decreases in intensity.
Karl will then track in between Iceland and the U.K. around Tuesday of next week.
Karl will follow a weaker depression set to deliver another round of rain and gusty winds to the U.K., especially western and northern areas, on Monday and Monday night.
How close Karl tracks to the U.K. will determine the magnitude of the gusts set to buffet northern areas, but all signs point toward the first windstorm of the season unfolding in Scotland, Northern Ireland and far northern England.
Based on the current track of Karl, the strongest winds will remain north of the U.K. However, AccuWeather Meteorologist Tyler Roys said winds on Tuesday could gust to 50 mph with localized areas up to 75 mph.
"The strongest winds would mainly be in the typically open and windier locations of the northern U.K," he said.
Possible tree damage and power cuts may result. Such issues could be widespread in northern and western Scotland and on a more sporadic level in Belfast and Edinburgh.
"The winds could also cause transportation disruptions, rough seas and minor coastal flooding, especially at high tide," Roys said.
West-facing communities of Scotland are at greatest risk for the coastal flooding. More severe coastal flooding could occur along the western shores of the Outer Hebrides if the peak wave heights occur at the time of high tide.
Waves in excess of 20 feet may pound the western shoreline of the Outer Hebrides.
The windstorm will be accompanied by blustery showers. Latest indications keep the heaviest rain of Karl north of the U.K., which would prevent the risk of flooding.
While the windstorm rages to the north, scattered blustery showers will dampen Wales and southern England. Wind gusts in the southern U.K. will likely remain below 35 mph. Such gusts could still interfere with outdoor activities and toss around trash cans or other loose lawn items.
Temperatures in the southern U.K. will range from 16-20 C (60-68 F) on Tuesday. While these highs are slightly above normal, the showers and gusty winds will cause AccuWeather RealFeel® temperatures to be lower than actual temperatures at times.
Less than 24 hours after Karl departs, another depression could bring yet another bout of rain and wind to the U.K. by Wednesday night into Thursday. Before reaching the U.K., the depression will first absorb Tropical Storm Lisa.
