There is an area of low pressure that is producing some thunderstorms about 1100 miles southeast of Hilo, Hawaii.
Environmental conditions appear conducive for additional development of this system, and a tropical depression could form during the next couple of days.
The low is expected to move west-northwest.
Upper-level winds are expected to become less conducive for development during the latter part of the week.
The Central Pacific Hurricane Center gives the low a 40 percent chance of becoming a tropical cyclone over the next five days.
