WASM — A regional rainstorm is expected to begin at the end of the week over parts of the Levant and northwest Saudi Arabia, becoming intense and wide‑ranging as a deep low‑pressure system centers over northern Egypt by mid and late next week, bringing high risk of a regional flash‑flood event.
Highly moist and strongly disturbed equatorial waves from the Arabian Sea will deepen into the Arabian Peninsula starting at the end of the week, coinciding with the approach of several low‑pressure systems — one of which will be centered over northern Egypt at the end of the month — leading to a widespread and heavy regional rainstorm.

The rainstorm begins at the end of the week and early next week over wide parts of western Saudi Arabia, Hail, western Qassim, Al‑Jouf, parts of the Northern Borders, and extends toward Iraq and the Levant — especially central and southern Syria, including parts of Damascus and northeastern Jordan.
