TROPICAL STORM HILARY: UPDATED 9 AM SUNDAY 8-20-2023

As expected, Hilary has weakened to a Tropical Storm. It will still bring rain and intermittent downpours through the day and early tonight. Showers will dissipate by 7 AM Monday. Rain totals still look to be 1.5" to 2.5" for coastal and inland areas. Mountains will be 3" to 6".

Winds will be strongest from noon to 8 PM in the mountains and desert, where gusts could reach 65 mph. Winds will strongest on the coast and inland from 3 to 10 PM, where gusts could reach 45 mph.

 

 

HURRICANE HILARY: UPDATED 1 PM SATURDAY 8-19-2023

The satellite imagery below shows how the once well-defined eye wall of Hilary has now collapsed. In addition, Hilary has broadened and looks more ragged on the edges. These are all signs of a rapidly weakening hurricane.

Regardless, this system is still headed our way and the pace has accelerated. Most computer forecasts (shown below) have the storm weakening to a Tropical Storm by the time to passes overhead midday on Sunday. The real threat from Hilary will be the heavy rain and potential for flash flooding.

Showers will develop to the east in the desert and mountains this evening and tonight. Those showers will migrate westward early Sunday morning. Periods of rain and downpours will then arrive midday as the core of Hilary passes overhead. This will occur between 12-5 PM. 

Lingering showers an isolated downpours will still be possible Sunday evening and Sunday night as the storm exits the region. Most rain will be gone Monday morning.

I've posted the official track from the National Hurricane Center and also the computer projected rain totals from Hilary. San Diego should see 1.5 to 2.5", though in the mountains, totals will range from 4" to 7" (isolated areas could get more).

As always, check with the National Weather Service San Diego for all the latest warnings and advisories.

 

 

 

NEXT RAIN CHANCE SAN DIEGO: HURRICANE HILARY UPDATE, 8 PM THURSDAY 8-17-2023

Hurricane Hilary currently has winds of 120 mph. The eye is well-defined with some healthy convection around the center. It's looking a little ragged on the edges, which is usually a sign of some shearing. 

Most of the computer data has it moving along the western coastline of the Baja. Hilary will continue to weaken as it moves into colder waters.

Some outer bands of rain could reach San Diego on Saturday. A quick shower or downpour could pop up at any point, though it won't be a washout.

A better chance for rain arrives Sunday as the core of the storm moves closer. The best chance for more consistent periods of rain and downpours will arrive Sunday evening/night through early Monday.

As with any tropical system, rain totals will be greatly impacted by the track of the storm. The slightest shift could reduce the computer projected rain totals I've posted below. Right now, the projection shows over 2" of total rain in San Diego.

Although most of this rain will quickly rush back into the ocean, it will be nice to get some rainfall back into the area.

I'll post an update tomorrow or Saturday morning, especially if it looks like there will be a change in storm track.
