Saudi Arabia: Thunderstorms intensify and spread to seven regions. Here are the details of the areas affected.

Arab Weather - The weather forecasting team at the Arab Weather Regional Center reported positive updates to the region's weather maps, expected to positively impact the intensity and coverage of seasonal rains in the western part of the Kingdom today and over the coming days. Larger amounts of tropical moisture will flow into the region, causing widespread cumulonimbus clouds to form.

Heavy thunderstorms, sometimes accompanied by downward winds and hail, are expected in parts of Jazan, Asir and Al-Baha.

In detail, the latest outputs from our computer simulation systems for rain forecasts at ArabiaWeather indicate that the frequency and extent of thunderstorms will intensify further on Thursday and in the coming days, God willing, with thunderstorms extending from Jazan to Medina.

Although the weather will tend to be stable in the morning hours, cumulus clouds will begin to form in the skies of the region starting from the afternoon hours, so that they will quickly develop into cumulus thunderstorms in the skies of Jazan, Asir and Al-Baha, accompanied by lightning, thunder and hail showers in some locations, which may cause valleys and torrents. Rain will also include, but with less intensity, parts of Najran and the far south of the Riyadh region.

Tropical humidity is deepening further north and includes various parts of Taif, Makkah and Madinah.

Thunderstorm activity is also expected to affect Taif, the eastern parts of Makkah, and possibly the holy sites. It's possible that some of these clouds could move westward toward some of the Makkah region's coasts, potentially affecting Jeddah with downdrafts that would stir up dust and sand.
