SITUATION OVERVIEW
------------------
Tropical Storm Rachel is currently 800 miles southwest of San Diego,
moving northeast towards Northern Baja. Rachel is expected to make
landfall somewhere near the US/Mexico Border late Saturday night.
Tropical storm level impacts have the potential to reach San Diego
County. A Tropical Storm Watch is in effect for all of San Diego
County. The main concerns with Tropical Storm Rachel are coastal
flooding, wind, and periods of heavy rain. The majority of impacts from
the tropical storm are expected on Sunday.
South swell from Tropical Storm Rachel will arrive on Sunday. The
combination of the swell, increased onshore winds, and high tides over
7 feet will maintain a threat of coastal flooding and beach erosion
along beaches in San Diego County. Surf on Sunday is currently
expected to be 6 to 9 feet, decreasing to 3 to 6 feet for Monday and
Tuesday. Confidence in impactful coastal flooding is high, with
significant coastal flooding and beach erosion increasingly possible.
Widespread rain is expected on Sunday from Tropical Storm Rachel.
There is expected to be a gradient in rainfall amounts with the higher
amounts on the southeastern side of the storm. We have the highest
confidence that the heaviest rain will occur over San Diego county
mountains and deserts. Peak rainfall rates of 0.50 to 0.60 inches are
possible for the coast and valleys, 0.50 to 0.70 inches per hour
possible for the deserts, and 0.70 to 1 inch per hour for the
mountains. Current forecast has rainfall totals of 0.50 to 1.25 inches
for the coast, valleys, and deserts and 1 to 2 inches for the
mountains. Areas of flash and urban flooding are possible, especially
where the maximum rainfall rates occur. The San Diego River at Fashion
Valley is currently forecast to peak at 7.4 feet (which is just below
monitor stage) Sunday afternoon. Those with interests near the San
Diego River should continue to monitor.
Increased winds are expected with the onset and passage of Tropical
Storm Rachel. Sustained winds of 39+ mph are expected on the southeast
side of the storm. Based on the current track, more southern and
eastern parts of the county are most likely to see winds of this
magnitude. Regardless, strong sustained winds and wind gusts can be
expected on Sunday. Winds may be enhanced by local terrain with gusts
40 to 55 mph on the desert slopes of the mountains and into the
deserts. Local gusts up to 60 mph possible on mountain ridges.
POTENTIAL IMPACTS
-----------------
* WIND:
Prepare for hazardous wind having possible limited impacts across
EXTREME SOUTHWESTERN CALIFORNIA. Potential impacts include:
- Damage to porches, awnings, carports, sheds, and unanchored
mobile homes. Unsecured lightweight objects blown about.
- Many large tree limbs broken off. A few trees snapped or
uprooted, but with greater numbers in places where trees are
shallow rooted, especially in coastal and valley locations that
don't typically experience strong winds. Some fences and
roadway signs blown over.
- A few roads impassable from debris, particularly within urban
or heavily wooded places. Hazardous driving conditions on
bridges and other elevated roadways.
- Scattered power and communications outages.
* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts across San Diego County. Potential impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, arroyos, and
ditches may become dangerous rivers. In mountain areas,
destructive runoff may run quickly down valleys while
increasing susceptibility to rockslides and mudslides. Flood
control systems and barriers may become stressed.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or washed
away. Many places where flood waters may cover escape routes.
Streets and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous.
Many road and bridge closures with some weakened or washed out.
Prepare for dangerous rainfall flooding having possible significant
impacts across San Diego County.
* OTHER COASTAL HAZARDS:
High tides over 7 ft, combined with high surf and gusty onshore winds
will increase the threat for coastal flooding across area beaches.
Additionally surf of 6 to 9 ft will create dangerous swimming
conditions. There is increasing potential for significant coastal
flooding and beach erosion.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Follow the advice of local officials.
* OTHER PREPAREDNESS INFORMATION:
If you live in a place particularly vulnerable to flooding, such as
near the ocean, in a low-lying or poor drainage area, or in a valley,
plan to move to safe shelter on higher ground.
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.
Always heed the advice of local officials and comply with orders that
are issued.
Closely monitor weather.gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.
