Aviation

(00z TAFS) Issued at 426 PM PDT Fri Apr 26 2024

Satellite shows FEW to SCT clouds shuffling through the region but VFR and some clear skies over the terminals. Breezy and gusty westerly winds will continue to linger through early evening before becoming moderate overnight. Breezy conditions return late Saturday morning/early afternoon. VFR is expected to prevail through the TAF period for most terminals except Monterey Bay terminals.

Vicinity of SFO, VFR through the TAF period but a few models suggest MVFR returning overnight and clearing early morning, but had low confidence to include in TAFs at this moment and input a SCT group to hint at the possibility. Westerly winds will remain gusty through most of the early evening then diminish to moderate by 09- 10Z.

SFO Bridge Approach, Similar to SFO.

Monterey Bay Terminals, VFR through most of the TAF period but models show agreement of another round of MVFR conditions overnight with KMRY seeing ceilings as early as 02Z. Moderate confidence on exact timing but overall model agreement that MVFR will occur after 08Z for both terminals. Gusty westerly winds will diminish to moderate overnight before becoming breezy and gusty again by Saturday afternoon.

(tonight through next Wednesday) Issued at 426 PM PDT Fri Apr 26 2024

Strong northwesterly winds with gale force gusts are to be expected through the weekend, particularly over the coastal waters. Light rain will be possible over the waters today as a result of the passing weak cold front. Moderate period northwesterly swell will continue to move through the waters through Wednesday.
