Wildfire Danger Continues in Southern California

High pressure building into the Western U.S. will create strong offshore winds in southern California. Temperatures in this region are unseasonably hot, and conditions are dry. The combination of these strong winds and dry conditions will bring fire danger to portions of southern California. Red Flag Warnings are in effect here. Any new fires in this region could quickly grow out of control. Read More >

The resulting graphic displays forecast vertical wind profiles over the selected location from the surface up to 2,000, 5,000, 10,000, or 20,000 feet AGL.
The graphic is updated based on the latest run of the HRRR, RAP, HiResW, NAM, or GFS model.
You can also select "Multiple" to toggle among the models for a specific set of parameters.
Wind speeds are color-coded with with speeds 28-37kt displayed in blue, 38-47kt in pink, and winds greater than 47kt in red.
Wind direction is indicated by the staff using a 360° compass, where 180° indicates a south wind and 360° a north wind.
Tailwind/headwind is bold when ≥30kt and crosswind is bold when ≥15kt.
The airport declination is included in tailwind/headwind/crosswind calculations for most Pacific NW and major US airports.
The solid red line indicates the highest forecast freezing level over time.

Calcuations of low level wind shear (LLWS) are made from the surface to the top of each near-surface (≤2,000 ft AGL) sigma level.
Table output represents the layer with the highest LLWS (speed-height). Height of the layer is in hundreds of feet AGL.
NSS (No Significant Shear) is used when LLWS <5kt. LLWS >20kt is displayed in dark red, LLWS >30kt in bold lighter red.
