High fire danger with low relative humidity 25 percent or less and northwesterly breeze near 15 mph. Chilly Thursday morning in the mid-upper 40s. Warm afternoons and chilly mornings rest of the week. Slower arrival of next storm system means scattered showers are not expected now until late Sunday night into Monday. Seasonably cool temperatures for much of next week.

Tropical Storm Melissa drifting over central Caribbean Sea. The longer Melissa stays weaker, the better opportunity it has to move farther west over highest ocean heat content, and could rapidly intensify into a major hurricane. Melissa is expected to produce heavy rainfall across portions of Dominican Republic, Haiti, and Jamaica, bringing a risk of significant, life-threatening flash flooding and numerous landslides. Melissa is forecast to meander for several days under light stirring currents, then could slowly turn to the north feeling the frictional effects of nearby land masses per GFS outlier model solution, OR it could gradually continue westward as shown by ECMWF and Google Deep Mind models.
