San Diegans should brace for robust winds, as the National Weather Service of San Diego has placed a High Wind Watch in effect from Tuesday afternoon through Thursday morning. According to the NWS San Diego forecast, gusts could reach up to 75 mph in specific areas, including wind-prone passes and coastal mountain slopes. This high wind event will peak Wednesday morning, contributing to potentially hazardous conditions.
Further details released by the NWS highlight a moderate to locally strong Santa Ana wind event anticipated to begin late Tuesday afternoon and last through Wednesday. While these winds are more common this time of year, they're expected to be significantly stronger than usual, with gusts potentially to top 50 mph in regions such as the San Bernardino Mountains, below the Cajon Pass, and extending down into the Santa Ana Mountains and adjacent inland areas of Orange County. This has prompted authorities to maintain vigilance, with the understanding that such wind conditions can arise rapidly and unexpectedly during this season.
Inland temperatures are due to spike, with today's highs charting 4-8 degrees above normal, creating a mild warmth before a slight cooling trend near the coast begins Monday, according to NWS San Diego. While mild, warmer weather is anticipated today, a cooling trend is expected for Monday and Tuesday, followed by potentially warmer conditions starting Wednesday until the end of the week.
The NWS also warns of the potential implications for fire weather. Although relative humidity is projected to stay in higher ranges, the threat level for wildfires could increase should the current forecast trend towards drier conditions. With the return of offshore flow by Monday afternoon, the situation allows for only a brief reprieve before elevated wind conditions resume by late Tuesday, potentially escalating into a critical fire weather scenario by Wednesday afternoon if humidity levels drop significantly. Please be aware that this period is appropriate caution in vulnerable areas.
Marine activity will not be immune to the influence of the weather. Offshore wind strength is set to intensify Tuesday, continuing through late Wednesday evening. Boat operators are advised that wind gusts could reach 25-30 knots, leading to choppy conditions at sea, as noted in the Area Forecast Discussion. NWS encourages the community to stay updated on weather conditions as these wind patterns and temperature shifts could significantly impact both land and marine environments.
