The National Weather Service today issued an excessive heat warning for Westport and the tri-state area from noon Tuesday to 8 p.m. Wednesday.
A late afternoon advisory said the decision to elevate the alert from a watch to a warning was based on a forecast calling for high temperatures to climb into the mid 90s to near 100 degrees across the area Tuesday.
Combined with oppressively high humidity levels, this will result in heat indices climbing to between maximum levels of 105 to 110 degrees Tuesday afternoon, the advisory said. The highest heat indices are expected to occur between 1 p.m. and 6 p.m.
This dangerous heat wave will continue through Wednesday. High temperatures Wednesday will be similar to or even a degree or two hotter than Tuesday, climbing to the upper 90s to 102 degrees, the advisory said.
