Arab Weather - The latest weather maps from Arab Weather indicate the formation of the first major Atlantic storm of the season in the North Atlantic Ocean at the end of this week. It will impact northwestern Europe and directly impact the United Kingdom.

A weather bomb forms in the Atlantic for the first time this season.

ArabiaWeather forecasters said that the weather maps released by the agency indicate that atmospheric pressure in the North Atlantic Ocean will drop to very low levels by the end of next week, particularly on Friday and Saturday. This coincides with the formation of a very deep, stormy, and rainy low-pressure system that will directly impact Britain.

What is a weather bomb?

A weather bomb is a meteorological term used to describe a weather event that sees atmospheric pressure drop by 24 hectopascals or more within 24 hours. This is what weather maps indicate, according to the updates for Monday morning, September 29, 2025. The atmospheric pressure in the center of the Atlantic storm is expected to drop from 985 hectopascals to 935 hectopascals within 24 hours.

How does atmospheric pressure drop in this way?

Arab Weather experts say that the jet stream's meandering at this time of year is the main reason, after God's will, for the formation of this weather condition, as the large meandering of the jet stream causes very cold winds to rush towards the warm Atlantic waters. When these winds collide with the warm Atlantic waters, the atmospheric pressure drops rapidly due to the large temperature difference between the polar winds and the warm sea waters, until it reaches record and very low values approximately hurricane values in a very short time. The huge water surface area in the Atlantic Ocean also plays an important role in the development of such storms, as it gives them sufficient time to develop before weakening upon entering land.

Sub-cyclonic values and atmospheric pressure drops below 940 hPa

Strong winds expected

Weather forecasts indicate that atmospheric pressure will drop in the center of the Atlantic capital by the evening of Friday, October 3, to less than 940 hectopascals. This is a level that is likely to trigger strong winds, some of which may exceed 100 km/h and could uproot trees and destroy property.

Strong winds and very heavy rain expected in northern Britain

Approximately 100 mm in some areas

Arab Weather forecasters said that forecasts indicate that the low pressure system will be centered west and northwest of the United Kingdom on Friday. A highly effective air front is expected to cross the country, bringing strong winds and heavy to very heavy rainfall, exceeding 50 mm in less than 24 hours in some areas. This air front is also expected to affect parts of western Europe.
