* WHERE…San Francisco, Coastal North Bay Including Point Reyes
National Seashore, San Francisco Peninsula Coast and Southern
Monterey Bay and Big Sur Coast.

* IMPACTS…Dangerous swimming and surfing conditions and
localized beach erosion. Sneaker waves can unexpectedly run

their feet and quickly pull them into the cold ocean waters,
where currents will be stronger than normal. These waves can
also carry driftwood logs and other debris.

SPC Apr 19, 2025 Day 4-8 Severe Weather Outlook

Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0252 AM CDT Sat Apr 19 2025 Valid 221200Z - 271200Z ...DISCUSSION... ...Days 4-6/Tue-Thu -- Southern Plains... A low-amplitude west/southwesterly mid/upper flow pattern will prevail Days 4-6/Tue-Thu. South/southeasterly low-level flow across the western Gulf into the southern Plains will allow for northward moisture transport and daily diurnal destabilization. In the absence of any stronger shortwave troughs moving through the weak west/southwesterly flow regime, severe potential is uncertain and will likely be driven by mesoscale/local processes, precluding 15 percent probabilities at this time.
