The chances that rain and wind from Tropical Storm Erin will hit the East Coast have risen slightly this week.

The National Hurricane Center's prediction cone shows a westward trajectory, but doesn't paint a clear picture whether or not it's likely to impact the east coast of the United States. Spaghetti models, which represent a collection of predicted paths generated by multiple computer models, paint a more definitive picture as of Wednesday morning.

Those near East Coast beaches need to be wary of danger as Tropical Storm Erin is predicted to cause rip currents.
