Another spike in bushfire activity for Vic

Victorians are being warned to brace for severe fire conditions as another "spike day" approaches.

All districts but East Gippsland are expected to have very high or severe fire danger rating on Wednesday before fire conducive conditions subside on Thursday.

Victorian Emergency Management Commissioner Craig Lapsley says it follows the current season's trend of fire danger "coming in spike days where it's a single day or two days in a row but not in for day after day after day."
