HAZARDS AFFECTING LAND
----------------------
STORM SURGE: Storm surge is expected to produce significant coastal flooding in areas of onshore winds within the warning area. Near the coast, the surge will be accompanied by large and destructive waves.
WIND: Tropical Storm conditions are occuring within the Tropical Storm Warning area for the next few hours but should end later this afternoon.
RAINFALL: Through Thursday, Pamela or its remnants are expected to produce the following rainfall amounts:
Across the Mexican States of Sinaloa, western Durango, and northern Nayarit...4 to 8 inches with isolated maximum totals of 12 inches. This rainfall may trigger significant and life-threatening flash flooding and mudslides.
Across portions of central Texas and southeastern Oklahoma...3 to 6 inches with isolated maximum totals of 8 inches. This may result in considerable flash and urban flooding impacts.
SURF: Swells generated by Pamela will continue to affect portions of the southern Baja California peninsula, as well as southwestern and west-central mainland Mexico through today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
