+\subsection{The Weather}
+
+Weather provides an adverse condition which can affect everyone equally -- both \glspl{pc} and \glspl{npc}.
+
+Broadly speaking, unfavourable weather brings Fatigue, especially to those without the right clothing.
+Freezing snow and hailstorms can add complications to any \gls{adventure}, obscuring vision, inflicting \glspl{fatigue} every section of the day,
+\footnote{See \autopageref{daytimes} for the day's quadrants.}
+and even limiting movement.
+
+Each weather condition should be given some rating for the \glspl{fatigue} and other conditions.
+
+For example:
+
+\begin{itemize}
+
+  \item
+  Snowstorm (3):
+  Characters suffer 3 \glspl{fatigue} every quarter of the day (or 2 with warm clothing), and suffer a -4 penalty to spotting anything in the distance.
+
+  Every day, travelling distances are reduced by 3 miles (but inflict the same amount of \glspl{fatigue} as ever).
+  Therefore, a troupe marching 6 miles would normally suffer 6 \glspl{fatigue}, but in this case they would only manage to walk 3 miles.
+  Of course the snowstorm add an additional 3 \glspl{fatigue}, making 9 in total.
+  \item
+  Heatwave (4):
+  4 \glspl{fatigue} per quarter of the day, or just 2 with cooler clothes.
+  Anyone wearing armour is \emph{not} wearing weather-appropriate clothing.
+
+  Of course, this means someone standing around from morning to evening would suffer serious sunburn, doled out as 8 \glspl{fatigue}.
+  \item
+  Hailstorm (2):
+  2 \glspl{fatigue} without weather-appropriate clothing, lasts only one scene.
+
+\end{itemize}
+
+Adverse weather conditions inflict \glspl{fatigue} every quarter of the day -- the default is `3', but it could be any amount, depending on the weather.
+\footnote{See \autopageref{daytimes} for day quadrants.}
+This can be reduced by 2 \glspl{fatigue} by wearing weather-appropriate clothing.
+\footnote{Characters can purchase this clothing -- see \autopageref{warmClothes}.}
