Heavy thunderstorms are expected across much of Saudi Arabia, the NCM warns — bringing risks of flash floods, hail, strong winds and rough seas in several regions. Residents should monitor official advisories and avoid flood-prone areas.

Overview of the Forecast

The National Center for Meteorology (NCM) announced in its Wednesday weather update that rainfall will continue across most regions of Saudi Arabia. The NCM predicts moderate to heavy thunderstorms in parts of Makkah, Madinah, Qassim, Riyadh, the Eastern Province and the Northern Borders. These storms may lead to flash floods and come with hail and strong winds. Light to moderate rain is also likely in parts of Hail, Tabuk, and Al‑Jouf, and in some southwestern highlands. Fog is possible in some areas.

Red Sea Weather

• Wind direction: Northwesterly to northerly (north & central); southeasterly to southerly (south).

• Wind speeds: 18–40 km/h, reaching up to 50 km/h.

• Sea state: Moderate to rough; thunderstorms and rain expected near the Bab el‑Mandeb Strait.

Arabian Gulf Weather

• Wind direction: Southeasterly to southerly.

• Wind speeds: 10–35 km/h, reaching over 60 km/h in stormy areas.

• Wave heights: 0.5–1.5 m, exceeding 2.5 m in rough zones.

• Notes: The northern Gulf may see thunderstorms and rain; sea conditions will vary from slight to moderate and become rough where storms occur.

Hazards and Precautions

The combination of heavy rain, hail and strong winds raises the risk of flash floods, especially in low‑lying and valley areas. Residents in vulnerable regions should:

• Avoid valleys and flood‑prone zones during heavy rain.

• Never attempt to cross flooded roads or fast‑moving water.

• Follow coastal and marine advisories — fishermen and marine operators should delay or cancel trips when warnings are issued.

• Monitor updates from the NCM and local civil‑defense authorities.
