All Eyes on Hurricane Katrina

By Cegeon J. Chan
STAFF METEOROLOGIST


As of late last night, Katrina, a category 5 (the highest on the Saffir-Simpson scale), still packed maximum sustained winds of 160 mph. One of the most astonishing characteristics is the extremely low pressure. Yesterday evening, an observation indicated 902 mb, the fourth lowest on record in the Atlantic basin. Most hurricanes do not maintain an intensity this strong, but with warm sea surface temperatures and a lack of any large-scale features that could weaken Katrina, computer models show Katrina will make landfall between the eastern half of Louisiana and Gulf Shores, Alabama by the morning hours at least as a category 4 hurricane.

Since Katrina is massive (hurricane force winds extend outward over 70 miles and tropical storm winds extend up to 230 miles) and with Katrina’s wrath being forecasted along densely populated areas, this hurricane could likely break the record that Hurricane Andrew ($31 billion) caused in damage in 1992. Back in Boston, although most of the day should remain dry, any outdoor Orientation activities are in jeopardy as a band of pesky rain showers will linger along the coast causing the rain to turn off and on.

Forecast:

Today: Mostly cloudy. A chance of showers. Patchy fog in the morning. Humid with highs in the low 80s F (27 C).

Tonight: Mostly cloudy. A chance of showers in the evening, then showers likely with a chance of thunderstorms after midnight. Humid with lows in the mid 60s F (18 C).

Tomorrow: Showers likely with a chance of thunderstorms. Humid again. Highs in the upper 70s F (25 C).

Tomorrow Night: Mostly cloudy. Humid in the mid 60s F (16 C).
