Two good facets for Southern California as Hilary arrives. First, she’s losing power and has dropped into strong tropical storm strength. Second, she’s moving north very fast at 25 mph, which is contributing to the weakening. The storm event should be complete for the state in less than 24 hours. That said, the rain and flooding look to be the biggest issue for the region. [NHS Information]
Six to ten inches of heavy rain with sustained winds of 40 mph+, with higher gusts, can create major issues for an area of hard soil that doesn’t generally get large amounts of rain in a short period of time. Washed out roads, fallen trees, flash flooding and other significant risks associated with this scale of rain are the major concern. As with most storms of this type, if you are in higher elevation areas the wind will be much stronger.
Hurricane Center – {…] At 800 AM PDT (1500 UTC), the center of Tropical Storm Hilary was located near latitude 29.7 North, longitude 115.9 West. Hilary is moving quickly toward the north-northwest near 25 mph (41 km/h). Hilary is expected to accelerate even more as it moves north-northwestward to northward during the next day or so. On the forecast track, the center of Hilary will move near or over the northern portion of the Baja California Peninsula during the next few hours, and then move across southern California this afternoon.

All preparations should be completed and everyone in the zone of largest impact should remain indoors for the next 24 hours. Power failures are highly likely as the storm will knock out electricity throughout the region. [Good luck to those with EV’s] In the hours immediately following the storm, do not travel. Stay close to home as the emergency service and first responders will activate to the areas of greatest issue.
We have quite a few Treepers in this area. Check in when you can and if you need anything send us an email or drop a comment, I will be checking throughout. The biggest issue I would foresee is the potential for weakened infrastructure, roads, bridges and systems that perhaps have not encountered high pressure or stress for many years.
Always take these things seriously, but do not alarm yourself with dark imaginings. Be prudent, be wise and be safe. Focus on the immediate area around your home, pull your family in close, watch out for each other and mitigate risks from a 100-foot perspective. [If “it” (a risk or threat) is within 100′, that’s your focus.]
