Detailed Forecast


Synopsis: A broad weak ridge continues to weaken as a low pressure system moves into the East Central Gulf Monday. This low will cause southeast winds to increase along the coast. A tightened pressure gradient caused by troughing in Canada will also increase winds diurnally within the Inner Channels for the next few days. The area of high pressure builds once again later Monday allowing for gulf coast winds to once again become northwesterly.
