A gale-force, non-tropical area of low pressure located a few hundred miles west of the coast of Portugal is producing limited shower activity. This system could acquire some subtropical or tropical characteristics later today while it moves eastward to east-northeastward at 10 to 15 mph toward Portugal and northwestern Spain. By tonight, the low will encounter unfavorable environmental conditions, and further development is not expected.
Any window for development, however, appears brief. The opportunity for tropical or subtropical development should close by Sunday night, when the system is expected to encounter unfavorable environmental conditions.

Tropical wave to emerge off Africa Monday
A tropical wave is expected to move off the west coast of Africa on Monday, and an area of low pressure could form in association with the wave early this week. Environmental conditions are forecast to be marginally conducive for development, and a tropical depression could form by the middle to latter portions of the week while the system moves generally westward at 15 to 20 mph across the eastern and central tropical Atlantic.
