Tropical Storm Don continues to maintain maximum sustained winds of 40 mph, according to the latest advisory from the National Hurricane Center.
As Don turns more toward the west over the next couple of days, it should move over warmer waters, allowing some gradual strengthening. Don is not expected to impact land.
Also in the Atlantic basin are three tropical waves, including one in the eastern Atlantic with a 20 percent chance of developing over the next seven days.
In the Pacific, Tropical Storm Calvin is beginning to pass south of the Big Island of Hawaii. Maximum sustained winds are 50 mph.
A tropical storm warning is in effect for Hawaii County.
Tropical-storm-force winds are imminent or already occurring in the warning area. Rainfall up to 10 inches is possible for some areas, mainly along the windward slopes and southeast flank of the Big Island.
Latest hurricane season forecast:What deranged heat and sea temps tell us about hurricane season
Swells generated by Calvin will spread across the main Hawaiian Islands tonight. This will lead to a rapid increase in surf along east facing shores, with high surf continuing into Wednesday. This elevated surf will likely cause life-threatening conditions.
