Hurricane Hilary - Aug ‘23

They have it there so it can make more frequent flights instead of originating in Biloxi MS, their home base. As the storm gets closer they will increase the number and frequency of flights.

USGS | National Water Dashboard is a good map for this stuff because it has river, watershed and aquifer layers and a couple good topography sets. NWS Flood Watch and Warning zones polygons, past and forecasted precipitation totals and radar loops. Pretty much the factors you might want to consider regarding what happens after the water hits the ground. Generally, where the watershed line is, is where the water is going to split, usually but not always on an elevation line. Aquifers is where saturation will cause more pooling, and where more movement could be occurring that is not easily observable. The river or stream that’s more or less in the topographical low, often the centerline, of a watershed is where the water is probably going to go. Watershed detail becomes more fine as you zoom.

96-5300 as ‘TEAL77’
99-5309 as ‘TEAL81’
97-5305 as ‘TEAL78’
These are the current Hurricane Hunters that are assigned to recon for Hurricane Hilary. Staging is out of KSMX (Santa Maria Public Airport) in Santa Barbara County. ‘TEAL77’ is the only aircraft so far to finish a recon flight. As stated above they have been moved to KSMX for shorter flight times as to allow more time inside the storm due to fuel limitations when lifting from Biloxi.

If all this comes true HWY 395 should be a fun drive during that time period.

People are saying this is the FIRST Tropical Storm of Southern California. FALSE! That storm occurred in September 25th, 1939. After the 1939 storm that killed 100 people the NWS opened its first Southern California office in 1940. The National Hurricane Center was formed in 1955. Long after the 1939 storm had occurred. Just to let you all know the National Weather Service was founded in 1870, before NOAA, NHC, and way before the NWS Severe Storm Prediction Center. With that being said, the NWS did form a Tropical Storm Watch for the 1939 storm, but the NHC could not because, it wasn’t around. Therefore, this proves this isn’t the FIRST Tropical Storm watch for Southern California!

Just for clarification……you are correct as far as the 1939 storm being the last. I think what folks are hearing and reading is that this is the 1st tropical storm watch…now warning ever issued for SoCal

Good point on what the NWS called storms when it began in 1870 - tropical watches or warnings. NHC began in 1950 - this is the first since then but not in the history of Ca. tropical storms.

Looks like a lot of rain either way:

The hurricane hunter plane found that the storm is still a category 4 hurricane with a minimum central pressure of 946 MB and maximum 130 MPH winds. The storm likely peaked in intensity a few hours ago and is now starting to weaken as it encounters wind shear and cooler waters.

TEAL 79 has been airborne for just under an hour and is off the coast of Rosarito, so we should be getting some greater insight on how things look shortly
