Overview
- The National Hurricane Center is monitoring three separate Atlantic systems, a northeastern non‑tropical low, a weak subtropical low near Bermuda, and a tropical wave off West Africa, per Saturday reporting from multiple NHC products.
- A strong non‑tropical low several hundred miles west‑northwest of Portugal has about a 20% chance of briefly gaining subtropical or tropical characteristics before conditions turn unfavorable by Sunday night.
- A weak trough a few hundred miles east‑southeast of Bermuda is producing disorganized showers and has low odds of slow development, pegged at roughly 10% over 48 hours and 20% over seven days.
- A tropical wave is expected to move off the west coast of Africa on Monday and may spawn a low; the NHC gives it near 0% odds over 48 hours and about 40% over seven days as it moves west across the tropical Atlantic.
- Forecasters link the muted Atlantic activity to a strong El Niño, increased upper‑level wind shear and Saharan dry air, and they caution mariners and nearby coasts to expect stronger trades, rough seas and localized heavy rain even if systems do not become storms.
