NOTE: We've guessed that you're not using a client that supports colored tables and have tried to compensate. Low graphics mode looks much better on clients that do... we recommend switching to Netscape 3.0 or Microsoft Internet Explorer.

Microbursts
coupled with developing rain shaft

Developing rain shafts often have a fuzzy, bulbous appearance as they descend. If a source of dry air is present and the air into which the rain is falling is sufficiently warm, then strong, and possibly damaging microbursts are possible.

. . . finally reaching ground within several minutes. The greatest threat of microbursts will be within 5 or 10 minutes either side of the precipitation "touchdown."
