Mainly dry conditions expected today along with very little cloud cover. This combined with a southerly flow will make for another day of very warm and humid conditions for the island chain. Heat index values this afternoon will peak near or slightly above 100°. Expect little to no relief overnight as heat index values will remain in the 90s. As a result our heat risk is Limited (1 of 4) to Elevated (2 of 4) through at least the next 24 hours. If you're planning on being outdoors for an extended period of time, make sure to seek shade and drink water often. Also, be sure to check on your neighbors, especially the elderly, those sensitive to heat, or persons lacking air conditioning.
