DISCUSSION
A TROPICAL WAVE WILL MOVE SOUTH OF THE REGION TODAY, WITH ITS
MOISTURE FIELD REACHING THE AREA AND PROVIDING SOME RELIEF IN

HUMIDITIES IN THE LOW 50S CONTINUING TO BE POSSIBLE. WINDS WILL
BE FROM THE EAST-SOUTHEAST AT 10 TO 20 MPH, WITH GUSTS UP TO
33 MPH, ESPECIALLY FROM MID MORNING INTO THE AFTERNOON. A FIRE
DANGER STATEMENT COULD BE ISSUED LATER TODAY IF THE MOISTURE
FIELD FROM THE TROPICAL WAVE MOVES FURTHER SOUTH. AN ELEVATED
HEAT RISK WILL ALSO PERSIST OVER THE AREA AND SAHARAN DUST
