Beta has the potential to produce a long duration rainfall event along the western Gulf Coast. Today through Tuesday, Beta is expected to produce rainfall accumulations of 8 to 12 inches with isolated totals of 20 inches beginning Saturday across southern Louisiana and spreading into coastal Texas on Sunday. Flash and urban flooding is likely as well as minor river flooding. Additional heavy rainfall amounts across the western Gulf Coast are possible through late week as Beta is expected to move slowly near the Texas coast.
