There are no watches, warnings, or advisories at this time.

Winds will increase out of the west to southwest Thursday afternoon. Gusts 25-40 mph will result in stronger crosswinds on north to south highways, reduced visibility from blowing dust, and choppy lakes.
A system coming in this weekend has the potential to bring impactful rainfall, but there is significant uncertainty in total rain amounts. This is due to the uncertainty in the precise track of the low pressure system moving through Saturday night into Sunday. There is nearly an inch difference between low end and high end rainfall amounts. Higher rainfall amounts could result in rises on small streams and creeks, alongside flooding and triggering debris flows. Additionally, breezy north winds and isolated thunderstorms are also a threat. Please continue to monitor the forecast through the week to be aware of any changes.
