Rainclouds associated with Invest 94W will slowly overspread Guam and the rest of Marianas Islands today and into tomorrow. The overall forecast track of 94W, based on computer models, takes it to the northwest past the islands and a recurve to the north by the latter part of the week.

We'll have more information in our afternoon update.
