KJ's First Warning Forecast

Hot, muggy and mainly dry Sunday with isolated storm chances during the afternoon. Highs in the mid/upper 90s with heat index values of 105 to 110. Be on alert for an elevated rip current risk if you're spending this hot day at the beach. Swells will gradually build over the next couple of days.

Iasias remains a tropical storm as of Sunday afternoon as it slowly works up the east coast of Florida with rain and wind along the coastal region.

Local impacts are likely to begin late Monday into early Tuesday. Expect scattered storms by Monday afternoon and evening with an isolated severe storm possible. Increasing rain chances throughout Monday night into Tuesday ahead of the Isaias.

A Tropical Storm Watch is in effect Tuesday for North Carolina's Outer Banks. Hazardous conditions are expected due to gusty winds upwards of 40 to 60 mph and seas of 10 to 16 feet. The watch includes parts of the adjacent Atlantic coastal waters, Albemarle, Croatan and Roanoke along with the Pamlico Sounds. In addition, Alligator, Neuse and Bay along with Pamlico and Pungo Rivers are included.

Despite it being a quick moving system unlike other long-duration tropical events, Isaias still poses a threat with wind, rain and potential flooding concerns for our region.

Tropical-storm-force winds could arrive overnight Monday into Tuesday. There's a 60 to 70% chance of tropical-storm-force winds (39+ mph) across northeast NC and southeast VA from 4 a.m. to 8 p.m. as the system enters and exits the region. Heavy rain is expected with 2 to 4 inches possible... Some localized higher amounts are likely to create some issues as heavier rain bands roll into the area Tuesday morning. Be mindful of areas prone to flooding, so turnaround if you encounter a flood covered road. It's important to not use wind as your threshold for how strong or weak the storm may appear. Prepare by removing any loose limbs, secure patio furniture and gather items for your hurricane supply kit.

Severe Threat: Wind damage is possible, brief spin-up tornadoes may occur Tuesday morning, strong onshore winds coupled with the tidal cycle may cause some flooding.

A non-tropical disturbance will hang around for the rest of the week keeping us unsettled. Expect lots of cloud cover and afternoon showers and storms. Temperatures will be closer to normal for August in the upper 80s due to the clouds and rain... Expect it to remain humid.
