Severe Thunderstorm Warning and Flash Flood Alert Issued for San Bernardino County
HESPERIA, Calif. – Residents of San Bernardino County are facing hazardous weather conditions as the National Weather Service (NWS) in San Diego has issued a Severe Thunderstorm Warning effective until 2:30 PM PDT today. The storm, notably identified at 1:09 PM PDT near Hesperia, is reportedly stationary and poses significant risks, including wind gusts up to 60 mph and quarter-sized hail.
Adding to the urgency, an Emergency Alert for a Flash Flood Warning was issued at 1:40 PM, which will remain in effect until 4:45 PM. The NWS cautioned the public, advising, “This is a dangerous and life-threatening situation. Do not attempt to travel unless you are fleeing an area subject to flooding or under an evacuation order.” The advisory emphasizes the dangers of flooded roads, highlighting that “most flood deaths occur in vehicles.”
Potential Impacts of Severe Weather
The latest reports confirm these hazardous conditions based on radar readings and local observations. These storms not only threaten property but also pose dangers to public safety, particularly for those in lower-lying areas prone to flooding.
- Wind Hazards: Residents can expect strong gusts reaching nearly 60 mph, capable of downing trees and causing structural damage.
- Hail Threat: Quarter-sized hail poses risks to vehicles and can cause injury.
- Flood Risks: The National Weather Service has cautioned against travel due to the potential for sudden flooding, particularly in roadways and low-lying areas.
Temperature Swings and Heat Advisory
Compounding the challenging weather patterns, a Heat Advisory is currently in place for coastal areas, where temperatures are expected to peak in the mid to upper 90s. This advisory will remain effective until Monday night, posing health risks for those without adequate cooling options.
Inland regions, including areas like Ramona, Escondido, and Alpine, may even experience record highs, with temperatures ranging between 102 to 110 degrees. Such extreme heat stresses the importance of hydration and taking breaks to maintain health.
Safety Recommendations
In light of the severe weather and excessive heat warnings, residents are urged to stay informed about the latest developments. Here are some recommended precautions:
- Stay indoors during the storm, if possible.
- Avoid traveling until the weather conditions improve.
- Heed warnings and advisories from local authorities.
- Seek cooling centers if you lack air conditioning, especially during the heat advisory.
Monsoonal Moisture and Thunderstorm Development
Forecasts indicate that monsoonal moisture will continue to trigger thunderstorms, particularly over the mountains and deserts today, with a better chance for precipitation than previous days. Thunderstorms may be capable of producing up to half an inch of rain, along with gusty winds and lightning, which can compound safety risks for the affected regions.
Outlook for the Week Ahead
Looking further ahead, the wind patterns are expected to shift on Monday, though storm development may still occur in the mountainous areas. As we move into Tuesday, the air is likely to dry out, leading to a cooling trend. By late this week, temperatures are anticipated to drop closer to average levels, providing some relief from the intense heat experienced earlier.
Residents are reminded to take these weather advisories seriously and prepare for the possibility of severe weather as conditions change throughout the region. For more detailed updates and weather forecasts, tune into local news or visit the National Weather Service website.
