Puerto Vallarta, Mexico - Puerto Vallarta saw heavy rains Wednesday night as another tropical storm spinning in the Eastern Pacific threatens catastrophic flooding in areas recently affected by Hurricane Norbert.

On Wednesday morning, an area of disturbed weather southwest of Mexico strengthened into a depression, then into Tropical Storm Odile. This system is expected to continue slowly shifting northward through the end of the week, then pick up more speed as it strengthens.

Odile will likely become a hurricane by the start of the weekend. Unlike the recent path of Hurricane Norbert, Odile is more likely to hug the Mexican coastline, with it's eye forecasted to pass just off the coast of Puerto Vallarta on Saturday.

From Manzanillo to Puerto Vallarta, coastal cities and the mountains just inland should expect the greatest impact, with heavy surfs, rains and winds beginning Friday and continuning through Sunday. While the heavy rain threatens mud slides, flooding rains will be possible closer to the coast.

According to AccuWeather.com Meteorologist Adam Douty, "the worst conditions will remain to the north of Acapulco. However, some locally heavy showers and storms could still move over the city through Saturday as tropical moisture gets pulled into the area."

Into the weekend, the storm will race to the northwest, heading for the southern tip of Baja California. Odile will be zoning in on areas that endured flooding rainfall from Hurricane Norbert just a week earlier.

As much as 2-3 inches (50-75 millimeters) of rain could fall on these areas in only a few hours. After the extensive flooding across Baja earlier this month, it will not take much more to cause additional flooding issues.
